Question

What is the pH of the resulting solution when equal volumes of 0.1 M NaOH and 0.01 M HCl are mixed ?
(a) 12.65
(b) 2.0
(c) 7.0
(d) 1.04

Answer 1

ans is ...........(a)12.65

Answer 2

for this we need,

m.eq of NaOH and HCl.

m.eq NaOH=0.1v

". ". HCl. =0.01v

(OH-)=(0.1-0.01)/2

OH- =0.045

poH=1.346

PH=14-1.346

=12.65,,,

option(a)...
