whats the solute of Chromium(III) chloride(aq) + potassium sulfide(aq)

Since both salts are in an aqueous solution I would call the solute water.

I believe you guys mean solvent ...

I meant solvent. Don't know what Freddy meant. Hard to tell.

To find the solute in the reaction between chromium(III) chloride (CrCl3) and potassium sulfide (K2S), we need to identify the ions that make up the solutes.

Chromium(III) chloride dissociates into its constituent ions in water:

CrCl3(aq) → Cr3+(aq) + 3 Cl-(aq)

Similarly, potassium sulfide dissociates into its constituent ions:

K2S(aq) → 2 K+(aq) + S2-(aq)

In this reaction, the solute is the substance that gets dissolved in the solvent (in this case, water). Therefore, the solute is made up of the ions Cr3+ and S2-.

So, in the reaction between chromium(III) chloride and potassium sulfide, the solute consists of the ions Cr3+ and S2-.
