Yes, monopotassium phosphate (MKP), with the chemical formula KH₂PO₄, is classified as a salt. It is formed from the neutralization reaction between a strong acid (phosphoric acid) and a weak base (potassium hydroxide). In general, salts are ionic compounds that result from the reaction of an acid and a base, and monopotassium phosphate fits this definition. It is commonly used in fertilizers and as a food additive.
