The saline hydrides react with water to form metal hydroxide and liberate hydrogen gas.

reaction-   MH+H_{2}O\rightarrow MOH+H_{2}   [M = Na, K, Ca...]

when added to the organic compounds they form metal hydroxide along with the liberation of hydrogen gas (escape into the atmosphere) and leave behind only hydroxide part.
