The H-, hydride ions can aggressively react with water to liberate hydrogen gas, causing the solution to become alkaline and include LiOH and Al(OH)3. As a result, the pH rises more than 7. The following illustration depicts the reaction of lithium aluminum hydride, LiAlH4, with water. LiAlH4 + 4 H2O → LiOH + Al(OH)3 + 4 H2 Since it has a strong basicity, it can react with protic solvents like methanol in addition to water.
