How do potassium hydride react with water write balanced chemical equation?
KH+H2O→K(OH)2+H2.
Does hydride react with water?
Hydrides such as calcium hydride are used as desiccants, i.e. drying agents, to remove trace water from organic solvents. The hydride reacts with water forming hydrogen and hydroxide salt.
Can potassium react with water?
It reacts with water more rapidly than does sodium, which is placed higher in the periodic chart. Potassium is non-water soluble, but it does react with water as was explained earlier. Potassium compounds may be water soluble.
What type of reaction is potassium and water?
single replacement reaction
An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
How does calcium hydride react with water?
Calcium hydride reacts with water to form calcium hydroxide and hydrogen gas.
What happen when LiH is treated with water?
LiH reacts with water in a predictable manner to generate hydrogen gas and an aqueous LiOH solution.
Is LiH soluble in water?
Lithium hydride

Why does potassium react with cold water?
(a) Potassium (K) reacts with cold water to form potassium hydroxide and hydrogen gas.
How does potassium chloride react with water?
2: As potassium chloride (KCl) dissolves in water, the ions are hydrated. The polar water molecules are attracted by the charges on the K+ and Cl− ions.
What happens when sodium and potassium react with water?
In this dramatic demonstration, lithium, sodium, and potassium react with water to produce hydrogen gas and the hydroxides of the metals. Lithium reacts fairly slowly, fizzing.
How does potassium react with cold water?
How does calcium carbide react with water?
Calcium carbide is not volatile and not soluble in any known solvent, and reacts with water to yield acetylene gas and calcium hydroxide. Its density is 2.22 g/cm³. Its melting point is 2160 °C, and its boiling point is 2300 °C.
