Question

The hydrogen ion concentration in a mixture of 10 mL of 0.1 M H2SO 4 and 10 mL of 0.1 M KOH solution in water, is (A) 0.1 M (B) 0.05 M (C) 0.2 M (D) 0.02 M

Tardigrade Admin · Accepted Answer

Number of moles of H2SO4 = 0.1×10= 1 Number of moles of KOH = 0.1×10 = 1 As number of moles of KOH and H2SO4 are same, i.e. KOH is completely neutralising H2SO4. ∴ The resulting molarity of a mixture will give the hydrogen ion concentration. MV = M1 V1 + M2 V2 M(20)=1+1 M=(2/20)=0.1
