Question

Equal volumes of 0.1 M HCl &
0. 1 M NaOH are mixed. The conc
of the resulting solution will
be?​

Answer 1

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
