What acid react with KOH to produce the salt KCl?

Answer 1

Hydrochloric Acid (HCl), because HCl in aqueous solution form ions H^(+) & Cl^(-)

It is the Cl(-) anion that combines with then potassium cation to form that salt potassium chloride (KCl).

Here is the balanced reaction eq'n

HCl(aq) + KOH(aq) = KCl(aq) + H2O(l)

Answer 2

Hydrochloric acid, HCl. HCl + KOH ===> KCl + H2O However, potassium chloride is soluble in water, so there would be no visible precipitate. Just potassium ions and chloride ions in solution.

Answer 3

The reaction is:
KOH + HCl = KCl + H2O
HCl is hydrogen chloride.
