Julli [10]

NaHS is an acidic salt.

NaHS is obtained by replacement of one acidic hydrogen of `H2S` by Na (on reaction with NaOH).

<h3>What do we know about NaHS?</h3>

The chemical compound with the formula NaSH is sodium hydrosulfide. This substance is created when hydrogen sulfide is partially neutralized with sodium hydroxide. In the industrial setting, sodium sulfide and NaSH are frequently employed for the same things. Solid NaSH has no color.

Solution of sodium hydrosulfide is a colorless to light-yellow liquid. corrosive to flesh and metals. It is employed in the production of colors and paper pulp.
