The chemical equation for the reaction between hydrochloric acid and potassium hydroxide is: KOH+HCL=KCL+H2O. The reaction between the two produces potassium chloride and water, with no obvious phenomenon.

When dilute hydrochloric acid and potassium hydroxide react, the hydrogen ions in the dilute hydrochloric acid combine with the hydroxide ions of potassium hydroxide to form water, but the phenomenon is not obvious. If you want to prove the reaction between the two, you can add phenolphthalein reagent dropwise to the potassium hydroxide solution, and the solution will turn red; then add dilute hydrochloric acid dropwise to the potassium hydroxide with phenolphthalein reagent added dropwise, and you will see the red color gradually fade away. This proves that dilute hydrochloric acid and potassium hydroxide react to form water and salt.

Introduction to potassium hydroxide

Potassium hydroxide is a common inorganic base with the chemical formula KOH and is a white powder or flake solid. Potassium hydroxide is alkaline and corrosive and generates large amounts of heat when dissolved in water, alcohol or treated with acid. Potassium hydroxide is widely used in the pharmaceutical industry, light industry, dye industry, and textile industry.
