What is the pH of the resulting solution when equal volumes of 0.1 M NaOH and 0.01 M HCl are mixed ? Option 1) 12.65 Option 2) 2.0 Option 3) 7.0 Option 4) 1.04

As we learnt in concept

Value of p(H) -

Acidic solution has p(H)  < 7

Basic solution has  p(H)  > 7

Neutral solution has p(H) = 7

-

Let volume of each solution be 1L

moles of NaOH=0.1ml

moles of HCl=0.01ml

moles of NaoH left after mixing =0.09ml

Malarity =normality (as n=1)=
