Potassium carbonate, K2CO3, sodium iodide, NaI, potassium bromide, KBr, methanol, CH3OH, and ammonium chloride, NH4Cl, are solub
just olya [345]

Answer:

A. K₂CO₃

Explanation:

The chemical reaction showing the ions produced on dissolving Potassium carbonate in water is:

K₂CO₃ ⇒ 2K⁺ + CO₃²⁻

Number of ions produced = 2 + 1 = 3

The chemical reaction showing the ions produced on dissolving sodium iodide in water is:

NaI ⇒ Na⁺ + I⁻

Number of ions produced = 1 + 1 = 2

The chemical reaction showing the ions produced on dissolving potassium bromide in water is:

KBr ⇒ K⁺ + Br⁻

Number of ions produced = 1 + 1 = 2

The chemical reaction showing the ions produced on dissolving ammonium chloride in water is:

NH₄Cl ⇒ NH₄⁺ + Cl⁻

Number of ions produced = 1 + 1 = 2

<u>The largest number of dissolved particles per mole of dissolved solute is produced by Potassium carbonate.</u>
