Answer #1

Q.No-01

The equivalence point is the exact point in a titration when moles of one titrant equal the moles of the substance being titrated.

The endpoint is the point where the system changes when the moles of the reacting titrant exceed the moles of the substance being titrated.

Q.No-02

Monoprotic acid is an acid which donates single H -atom.

For example:- Reaction between HNO3 & NaOH

HNO3 + NaOH NaNO3 + H2O

We can see in above example, stoichiometric ratio of acid and base ( 1: 1) required to complete the reaction.
