  1. Correct Answer – 3
    `N_(2)H_(4)` is weak base. It reacts with acids to form two series of salts. The salts are white ionic crystalline solids and are soluble in water.
    `N_(2)H_(4)+HXrarrN_(2)H_(5)^(+)+X^(-)`
    `N_(2)H_(4)+2HXrarrN_(2)H_(6)^(2+)+2X^(-)`
    Solution of hydrazine is usually concentrated either by distilation or by adding `H_(2)SO_(4)` to precipitate the salt hydrazine sulphate `N_(2)H_(4).H_(2)SO_(4)`.
