Question
2.5 mL of 
M weak monoacidic base (
) is titrated with 
M 
in water at 
. The concentration of 
at equivalence point is (
)
M 
M 
M 
M
M M M M The correct answer is: M
Weak monoacidic base e.g., 
is neutralised as follows
At equivalence point all gets converted into salt and remember! The concentration of (or pH of solution) is due to hydrolysis of resultant salt (
Volume of used up
Concentration of salt
(
should be estimated whether that can be neglected or not)
on calculating =0.27 (significant, not negligible)
