How do we calculate solution pH?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H_{3}O^{+}].
What is the pH of a 0.02 M solution of KOH?
pH=14−(1.57)=12.4 .
What is the pOH of 2.55 BA Oh 2?
Thus the pOH of the solution is – 0.71 and it is basic.
What is the pH of a .1 M solution of HCl?
What is the pH of a 1.0 M solution of a strong acid?
pH-values for very strong acids are easy to calculate because the concentration of H+ (or H3O+) is identical to the concentration of HCl in the solution. Thus with pH = -log concentration of H+ the 1 M solution of HCl will give the pH of -log 1 or 0 (Zero) because 10 ^0 = 1.
What is the pH of 0.00125 M HCl solution?
Hence the pOH of a 0.00125 M solution of HCl in water is 11.1.
How do you calculate pH on a calculator?
How do you find pH from pKb?
The Henderson-Hasselbalch equation states that pOH = pKb + log([salt]/[base]). Hence assuming you know the values of [salt] and [base] you can take the negative log of Kb. Adding pKb and log([salt]/[base]) will then give you your pOH value. From there subtract pOH from 14 to find pH as pH + pOH = 14.
What is the pH of a 0.10 M KOH solution?
Question: calculate the pH of 0.10 M KOH where KOH is a strong base. The answer should be above 7 since its a BASE.
What is the pH of a 1.9 10 ⁻ ³ M RBOH solution?
2 Answers By Expert Tutors
the [H^{1}^{+}] = 10^{–}^{14} / 1.9 x 10^{–}^{3} = 5.3 x 10^{–}^{12} . Take the negative log of this to get pH = 11.3.

How do you find pH with KB and M?
The smaller pKa the stronger the acid. The smaller pKb the stronger the base. Usually pKa is reported for acids and bases – for bases it refers to the conjugate pair. A buffer solution withstands changes in pH when a limited amount of acid or base is added.
What is pKb value?
pKb is the negative base-10 logarithm of the base dissociation constant (K_{b}) of a solution. It is used to determine the strength of a base or alkaline solution. Kb = [B+][OH-]/[BOH] pKb = -log Kb. A large Kb value indicates the high level of dissociation of a strong base.
