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

NEET levelSingle correct optionDifficulty 1 of 3ie057

The pH of a $0.001 M$ solution of $NaOH$ at 298 K is

A $3$
B $10$
C $12$
D $11$

Answer: D

NaOH

is a strong base, so

[OH X^{-}] = 1 0^{- 3} M

and

pOH = 3

. Therefore

pH = 14 - 3 = 11

.

The pH of a 0.01 M solution of HCl at 298 K is NEET level
The pH of a 5x10^-4 M solution of Ba(OH)2 at 298 K (assume complete ionisation) is NEET level
For a weak monobasic acid HA of concentration 0.1 M and K_a=10^-5, the pH (using [H+]=sqrtK_a c) is NEET level
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
