Name the salt used for the following purpose: Fire extinguisher

Sodium hydrogen carbonate or sodium bicarbonate is used as a fire extinguisher. When heated to a high temperature, the chemical properties of this salt make it produce lots of carbon dioxide and remove oxygen. This reduces the amount of oxygen and puts the fire out. The reaction also produces a small quantity of water and sodium carbonate as by-products. It is a chemical compound with a formula NaHCO 3 .

Name the acid and base from which the following salt is formed. Sodium chloride

The salt is formed when an acid and a base react. Sodium chloride is obtained by the reaction between hydrochloric acid and sodium hydroxide to give sodium chloride and water. Hydrochloric acid is the acid and sodium hydroxide is the base. It is also known as Common salt and is a type of neutral salt since it carries no charge. Sodium chloride Acid- HCl Base- NaOH .

Name the acid and base from which the following salt is formed. Potassium sulphate

Salts are strong electrolytes and thus are almost completely ionised in water, they are mainly formed by neutralization reaction. Potassium sulphate is a neutral salt that is formed by the reaction between a strong base KOH and strong acid H 2 SO 4 . Potassium sulphate Acid-Sulphuric acid Base-Potassium hydroxide.
