choose one ionic compound from the following set of compounds
|
|
HCl
|
|
|
K2S
|
|
|
NH3
|
|
|
CH4
|
Explanation:
Detailed explanation-1: -Potassium sulfide | K2S | ChemSpider.
Detailed explanation-2: -The potassium ion has a +1 charge whereas sulfide ion has a-2 charge. The compound is neutral and hence it requires two potassium (K+) ions to compensate for the two negative charges of sulfide (S2-) ions. Therefore, the chemical formula for potassium sulfide will be K2S.
Detailed explanation-3: -Ionic compounds include salts, oxides, hydroxides, sulphides, and the majority of inorganic compounds. Ionic solids are held together by the electrostatic attraction between the positive and negative ions. For example, the sodium ions attract chloride ions and the chloride ion attracts sodium ions.
