    titration-->pure sulphuric acid

    1. The problem statement, all variables and given/known data
    Why pure/conc. sulphuric acid is not suitable to prepare a standard solution directly?

    2. Relevant equations

    3. The attempt at a solution
    I know that it is hygroscopic,but what does it mean?Why absorbing moisture from the air will affect the result of titration?
