Question

The compound sodium iodide is a strong electrolyte. Write the reaction when solid sodium iodide is put into water.

Answer 1

Answer:

NaI(s) → Na⁺(aq) + I⁻(aq)

Explanation:

The chemical formula of sodium iodide is NaI. When NaI is dissolved in water, it dissociates into sodium ions (Na⁺) and iodide ions (I⁻). One mol of NaI gives 1 mol of Na⁺ ions and 1 mol of I⁻ ions.

Therefore, the chemical equation for the dissociation is the following:

NaI(s) → Na⁺(aq) + I⁻(aq)
