Question

17. Consider the titration of a weak base (such as NH) with a strong acid (suc The pH of the solution at the equivalence point of the titration will be A) greater than 7.00 B) equal to 7.00 C) less than 7.00 D) none of the above

Answer 1

When a weak base ( NH₃ ) is titrated with strong acid ( HCl ) salt of weak base and strong acid will form which on hydrolysis produce H⁺ ion so solution will be acidic and P^H will be less than 7 .

Hence correct answer is option ( c )
