Acetic acid can react with insoluble calcium, magnesium salt and alkali in scale to form soluble acetate, thus achieving the purpose of scale removal. If there is no white vinegar in the experiment, rice vinegar can be used instead, but because the acidity of rice vinegar is weaker than white vinegar, the scale removal effect is poor.

The main component of white vinegar is acetic acid (chemical formula CH3COOH), and the main components of scale are calcium carbonate (chemical formula CaCO3) and magnesium hydroxide (chemical formula Mg(OH)2). Both calcium carbonate and magnesium hydroxide are water-insoluble salts, and acetic acid can react with calcium carbonate or magnesium hydroxide to generate new water-soluble salts, that is, scale removal.

Because there is acetic acid in vinegar, acetic acid reacts with scale, that is, water-insoluble calcium carbonate, and decomposes into water-soluble calcium ion scale, mainly magnesium chloride and calcium chloride. The scale that can react with acetic acid is mainly composed of CaCO3 and a small amount of Mg(OH)2. It can react with acetic acid (CH3COOH) to form soluble salts. The main component of vinegar is acetic acid, and the main component of scale is calcium carbonate. They produce soluble calcium salts by chemical reaction.
