Both are same.
Both are used in many chemical experiments in laboratory such as for titration,for boiling,for chemical mixing and so on.

Why do we Standardize a Solution?

Sometimes we should have to standardize Solutions (Reagents) before starting a chemical experiments because,it will allow us to get correct readings during the experiment whereas the exact concentration of the solution could be different.And as well as by standardizing a solution we could minimize the deviation of instrumental errors & random human errors too.Therefore,it is good to standardize and get actual concentration at the initiation of the experiment.
