NEET levelSingle correct optionDifficulty 1 of 3ie064

$10 mL$ of $0.1 M$ $HCl$ is diluted with water to a total volume of $1000 mL$ . The pH of the diluted solution is

A $2$
B $3$
C $4$
D $1$

Answer: B

Moles of

H X^{+}

= 10 \times 0.1 = 1

mmol in

1000 mL

, so

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

and

pH = 3

.
