From the chemical equation given:
H2SO4+2KOH--->K2SO4+2H2O
the two reactants, H2SO4 and KOH, are in 1:2 stoichiometric ratio.
No. of moles of KOH = 2* no. of moles of H2SO4
=2*0.1*0.033
The concentration of KOH = no. of moles / volume
=2*0.1*0.033/0.05
=0.132M

A mixture of ammonium hydroxide and ammonium chloride forms basic buffer solution.
The Hendrson's equation for he basic buffer solution is as given below.
pOH=pK
b
+log
[acid]
[salt]
Substitute values in the above expression.
pOH=5+log
0.1
0.1
=5
Hence, the pH of the solution is pH=14−pOH=14−5=9
