MolSynapse / Question bank / Ionic Equilibrium I / pH of strong and weak acids and bases, mixtures

NEET levelSingle correct optionDifficulty 1 of 3ie063

A solution has pH 9.3 at 298 K. Its pOH is

A $9.3$
B $5.3$
C $4.7$
D $14.0$

Answer: C

At 298 K,

pH + pOH = 14

, so

pOH = 14 - 9.3 = 4.7

.

The pH of a 0.005 M solution of H2SO4 at 298 K, assuming complete ionisation of both protons, is NEET level
The degree of ionisation of 0.1 M acetic acid (K_a=1.8x10^-5) is nearest to (use alpha=sqrtK_a/c) NEET level
A 0.1 M solution of a weak monobasic acid has pH 3.0. Treating ionisation as small compared with c, its pK_a is NEET level
10 mL of 0.1 M HCl is diluted with water to a total volume of 1000 mL. The pH of the diluted solution is NEET level
Compared with a solution of pH 6, a solution of pH 4 has hydrogen ion concentration that is NEET level
The pH of 0.1 M weak base BOH with K_b=10^-5 at 298 K (use [OH-]=sqrtK_b c) is NEET level
