Question

PH of solution obtained by mixing equal volumes of 0.3m HCl and 0.1m NaOH is

Answer 1

Answer: 1

Explanation: as your mixing acid and base

The steps are as follows

Answer 2

Answer:

When equal volumes of 0.1 M NaOH and 0.01 M HCl are mixed, the hydroxide ion concentration is

2

0.1−0.01

=0.045M

The pOH of the solution is pOH=−log [OH

−

]=−log 0.045=1.35

The pH of the solution is pH=14−pOH=14−1.35=12.65
