Question

On mixing 100ml of n/10 naoh with 200ml of n/10 naoh,the normality of final naoh solution is

Answer 1

hi there

No.of moles of HCl present

=100 x 0.1=10 milli moles

No.of moles of NaOO present

=50 x 0.2 =10 milli moles.

So on mixing 10 milli moles of HCl with 10 milli moles of NaOH will be neutral and it's pH=7.
