Question

Which of the substances listed below would produce ions when dissolved in water? 1.) HCL

2.) CO 3.) Nal

A.)1 and 2

B.) 1 and 3

C.) only 3

D.) All of them

Explanation please

Answer 1

Answer is option B = 1 and 3 (HCL and Nal)

An acid is a substance that produces hydrogen ions when disslove in water. Hydrogen chloride is a gas which when disslove in water it becomes hydrochloric acid. HCL is a strong acid, it dissociates into H+ and Cl- ions when disslove in water.

HCL + H2O ------> H3O⁺ + Cl^-

Carbon monoxide is a gas. When carbon monoxide dissolve in water the reaction is called water-gas shift reaction. This reaction describes the reaction of carbon monoixide and water vapour to form carbon dioxide and hydrogen.

CO + H2O ------> CO2 + H2

Sodium iodide is the ionic compound. Sodium iodide is form from the chemical reaction of sodium metal and iodine. Sodium iodide is the water soluble and it is mixed with 1:1 ration of Na⁺ and I^- ions. When sodium iodide dissolve in water it gives NaH2O⁺ and I^- ions.

NaI + H2O ------> NaH2O⁺ + I^-
