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>

Why is water not used as a solvent in paper chromatography​
bogdanovich [222]

Answer:

Because the kind of compounds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.
