What's the difference between hydrosulphide and hydrosulphite?

Hydrosulphide

Definition:

(n.) One of a series of compounds, derived from hydrogen sulphide by the replacement of half its hydrogen by a base or basic radical; as, potassium hydrosulphide, KSH. The hydrosulphides are analogous to the hydrates and include the mercaptans.

Example Sentences:

(1) Formic acid is a weaker inhibitor than cyanide and hydrosulphide anions.
(2) corneum in bovine epidermis has been examined in leather from which the epidermis had unintentionally been incompletely removed in the course of manufacture, during attack on the keratinous tissue by hydrosulphide ions at high hydroxyl ion concentration.

(2) The mechanism of NAD reduction with sodium hydrosulphite is proposed.
(3) The cytochemical use of azures A, B and C, propared with either N HCL and potassium metabisulphite or with sodium hydrosulphite in tissue sections were investigated.
(4) Reduction of the polynitrostyrene latex involved adding latex dropwise to a large excess of 6% sodium hydrosulphite-2 N potassium hydroxide solution with sodium lauryl benzene sulphonate as an emulsifier.
(5) The concentration of haptoglobin-haemoglobin complex in haemolysed serum was measured by reducing the sample with sodium hydrosulphite.
(6) Dahlia-SO2 prepared with sodium hydrosulphite is highly suitable when used at pH 4-0 to 5-0.
