What happens if you were to place a dilute solution that is in a bag made of a semipermeable membrane and were to then suspend it in a very concentrated solution? Water would move out of the suspended bag and the size of the suspended bag would decrease.
How can you tell whether a sugar solution is saturated or not Group of answer choices?
How can you tell whether a sugar solution is saturated or not? Add more sugar if it dissolves it is saturated. There will be a precipitate if the water is heated. As long as there are more water molecules than sugar molecules there is a saturated solution.
Would you expect to find more dissolved oxygen in polar or tropical ocean waters Why quizlet?
Would you expect to find more dissolved oxygen in polar or tropical ocean waters? Why? There would be more dissolved oxygen in the polar oceans because the solubility of oxygen in water decreases with increasing temperature. Red blood cells have a high concentration of dissolved ions.
Why does oxygen have such a low solubility in water?
Oxygen has such low solubility in water because it is a non-polar molecule and water is polar.
How does intermolecular forces affect solubility?
Main Idea: “Like dissolves like.” The stronger the intermolecular forces between solute molecule and solvent molecule the greater the solubility of the solute in the solvent. … Between two polar molecules the molecule with the smaller hydrocarbon portion (or the larger polar portion) is more soluble in water.
What is happening at the molecular level when a polar molecule like water interacts with a typical sodium ion?
What is happening at the molecular level when a polar molecule like water interacts with a typical sodium ion? the water molecule aligns such that the oxygen interacts with the sodium.
Does the concentration of chlorine in drinking water tend to increase or decrease as it leaves the water treatment plant and disperses into the community why?
Does the concentration of chlorine in drinking water tend to increase or decrease as it leaves the water treatment plant and disperses into the community? Why? Decreases. Evaporative processes and reaction with organic bacteria would decrease the chlorine concentration.
Which is true about dissolving a polar substance in water?
A. Which is true about dissolving a polar substance in water? The solvent particles are all nonpolar molecules.
Which is an effective way to determine whether a mixture contains dissolved ions?
When the temperature increases which compounds become more soluble in water? Which is an effective way to determine whether a mixture contains dissolved ions? Let the mixture sit overnight and observe whether particles eventually settle out.
What condition occurs when too much water moves into the cell and the cell membrane ruptures?
What factor will cause more sugar to dissolve in a saturated sugar solution?
A packet of granulated sugar would dissolve faster than a cube of sugar. The rate of dissolving would be increased by stirring or agitating the solution.
What happens when a solution becomes saturated?
Which would not increase the rate at which a sugar cube dissolves *?
Which would NOT increase the rate at which a sugar cube dissolves? adding more solute.
How is ozone produced in the upper atmosphere quizlet?
How is ozone produced in the upper atmosphere? It forms by nuclear decomposition of oxygen. It diffuses from the lower atmosphere. It forms by reaction of oxygen molecules with UV light.
Why are the melting temperatures of most ionic compounds far greater than the melting temperatures of most covalent compounds quizlet?
Why are the melting temperatures of most ionic compounds far greater than the melting temperatures of most covalent compounds? Ionic bonds are so much stronger than the intermolecular attractions between covalently bonded compounds.
How is the solubility of a gas affected by temperature quizlet?
As temperature increase results in a decrease in gas solubility while a decrease in temperature results in an increase of gas solubility in water. … Therefore the higher the temperature the more solute is dissolved in the solvent which makes the precipitate dissolve.
How does oxygen get dissolved in the water?
Oxygen dissolves in surface water due to the aerating action of winds. Oxygen is also introduced into the water as a byproduct of aquatic plant photosynthesis. When dissolved oxygen becomes too low fish and other aquatic organisms cannot survive. … As the water becomes warmer less oxygen can be dissolved in the water.
Does oxygen have a low solubility in water?
What affects the solubility of oxygen in water?
Dissolved oxygen solubility is affected by water temperature atmospheric pressure and salinity. Cold water can dissolve more oxygen than warm water. As the temperature goes up water releases some of its oxygen into the air. Water also holds less dissolved oxygen at higher elevations because there is less pressure.
Is polar and makes compounds more soluble in water?
If the solvent is polar like water then a smaller hydrocarbon component and/or more charged hydrogen bonding and other polar groups will tend to increase the solubility.
Which forces are responsible for dissolving polar substances in water?
Answer. The forces which are responsible for dissolving polar substance in water are polarity of water molecule and exceptional hydrogen bonding ability of water molecule.
Is water a polar solvent?
Water ( H2O ) is polar because of the bent shape of the molecule. It also acts as a polar solvent. it has one side that is positively charged and one side that is negatively charged. … The oxygen atom of one water molecule will bond with several hydrogen atoms of other water molecules.
What happens when something dissolves?
A solution is made when one substance called the solute “dissolves” into another substance called the solvent. Dissolving is when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. … They do this by pulling away the ions and then surrounding the salt molecules.
Under which of the following conditions would you expect the highest solubility of oxygen gas in water?
A gas is most soluble in water under conditions of high pressure and low temperature.
What happens when an ionic compound dissolves in water?
When turbidity in water increases the efficiency of chlorine?
When turbidity in water increases the efficiency of chlorine? Explanation: The presence of turbidity in water makes it difficult to obtain free residual chlorine. So it is preferred to apply chlorine after filtration when water is free from turbidity. 2.
Why does chlorine disinfection happen at the end of the water treatment process?
Chlorination may also be done as the final step in the treatment process which is when it is usually done in most treatment plants. The main objective of this chlorine addition is to disinfect the water and maintain chlorine residuals that will remain in the water as it travels through the distribution system.
What is the purpose of treating water with chlorine gas or ozone during water purification?
To finalize the purification process chemical disinfection (usually with chlorine or ozone ) or UV light is applied to the water to kill bacteria viruses and the hardy cysts produced by cryptosporidium and giardia.
Which substances in the table would most likely dissolve in water?
Sugar sodium chloride and hydrophilic proteins are all substances that dissolve in water. Oils fats and certain organic solvents do not dissolve in water because they are hydrophobic.
Which contributes to the polarity of a water molecule?
Water (H2O) is polar because of the bent shape of the molecule. … The highly electronegative oxygen atom attracts electrons or negative charge to it making the region around the oxygen more negative than the areas around the two hydrogen atoms.
Which method would increase the solubility of gas?
The solubility of a gas in a liquid will increase if: Lower the temperature of the solution and therefore lower the kinetic energy of the gaseous particles so they can escape the liquid phase less often.
