Question

All metal sulphides are insoluble in acidic solution if true right 1 else write 0.

Answer 1

In the given question the solubility of the Sulphide has been discussed. Sulphide can be soluble in various solutions therefore in the answer solubility of the metal Sulphide specially in acidic solution is discussed.

Complete Step by step answer:
Sulfide is an inorganic anion of sulfur which has the chemical formula ${S^{2−}}$ or we can say a compound containing one or more ${S^{2−}}$ ions. Solutions of sulfide salts are corrosive in nature.
The solubility of the compounds depends mainly on the pH of the solution. The alkali metals and alkaline-earth metals are the only sulfides that can have considerable water solubility.

There are only Some metal sulfides which are soluble in acid or can say acid-hydrolyzable they are Zinc Sulphide, Cadmium Sulphide, Nickel Sulphide, Copper Sulphide, copper Sulphide rather than that there are other insoluble sulfides such as iron Sulphide, Molybdenum Sulphide and others. Many sulfide salts are insoluble in acidic solution are lead Sulphide, Bismuth Sulphide, Copper Sulphide, Cadmium Sulphide, mercuric Sulphide, arsenic Sulphide and more.

Therefore, from the above discussion we can say that all metal sulphides are not insoluble in acidic solution. Some can be soluble and some cannot.

Hence, 0 all metal sulphides are not insoluble in acidic solution.

Note: The sulfides of all metals except barium, calcium, magnesium, sodium, potassium, and ammonium are insoluble in water. Barium Sulphide, Calcium Sulphide, and Magnesium Sulphide are sparingly soluble in water.
