How will you quenching sodium hydride?

Answer 1

one sodium hypochlorite molecule (molecular weight of 74.44) reacts with one molecule of sodium metabisulfite (molecular weight of 190.1), you'll need two and a half grams of metabisulfite for every gram of hypochlorite.

not knowing what surface or material you are trying to apply this to (IF any) cannot give directions on use.

It is important to note that the fumes produced by sodium metabisulfite include sulfur dioxide, a very irritating gas that can cause dangerous reactions, especially in people who have Asthma. Wear breathing protection (A cartridge respirator fitted with an acid gas cartridge works)

Answer 2

actually sodium hydride quenched with dry hydrochloric acid to gives sodium salt and leberates hydrogen gas.

Answer 3

NaH + H2O --> NaOH + H2

Hydrogen gas is formed, which drives the decomposition.

Answer 4

By adding about an equivalent amount of stron acid:

NH3 + H+ --> NH4+

Answer 5

The reaction is:
HCl + NaOH = NaCl + H2O

Answer 6

using methanol using methanol
