KCl+H2O

When KCl is added to water (H2O), it undergoes a dissociation reaction.

The reaction can be written as:

KCl (s) + H2O (l) → K+ (aq) + Cl- (aq)

In this reaction, the solid KCl dissolves in water to form aqueous K+ ions (potassium ions) and Cl- ions (chloride ions). These ions are surrounded by water molecules, resulting in a homogeneous solution. This process is known as solvation or hydration.
