1 Assignment 5 Hydrogen – The Unique Element
... Both molecular and saline hydrides are quite reactive. Group 1 and 2 hydrides react vigorously with water to produce hydrogen gas and a metal hydroxide. This means that they can be used as drying agents for solvents – the most commonly used in this regard is CaH2. p-Block molecular hydrides have dif ...
