Potassium bisulphate (KHSO4) is a chemical compound that is commonly used in the manufacture of fertilizers, dyes, and other industrial applications. It is a white crystalline solid with a molecular weight of 136.17 g/mol and a melting point of 197 °C.

The 500g quantity of potassium bisulphate refers to the amount of the compound present in the package or container. This quantity is commonly used in laboratory settings or small-scale industrial applications.

Potassium bisulphate is highly soluble in water, and its aqueous solutions are acidic due to the presence of H+ ions. It is used as a source of sulfur and potassium in the production of fertilizers, as well as in the manufacture of certain types of glass, ceramics, and pigments.

It is important to handle potassium bisulphate with care as it can be hazardous to health if ingested, inhaled, or exposed to skin or eyes. Therefore, appropriate personal protective equipment should be used while handling this compound.
