Question

State the pH of mixture of a strong acid and a strong base.

Answer 1

Acid Base neutralisation reaction will take place. 

• The solution will be acidic or basic depending on which component has been taken in excess.
• If V₁ volume of a strong acid solution of normality N₁ is mixed with V₂ volume of a strong base solution of normality N₂, then 

Number of H⁺ ions from I-solution = N₁V₁ 

Number of OH^– ions from II-solution = N₂V₂
