Question

find the name of any four salts and their uses​

Answer 1

Answer:

Sodium chloride is used as a food additive in the preparation of food, to give foods a salty taste. It is also used as a food preservative.

Monosodium glutamate (MSG) is another food additive used in food preparation to enhance the taste of foods.

Sodium hydrogen carbonate is found in baking powders. Together with acid salts such as potassium hydrogen tartrate, calcium hydrogen phosphate and sodium hydrogen phosphate, they react in the presence of water to produce carbon dioxide. As the carbon dioxide escapes, it helps to make the cake or bread rise.

Sodium nitrite and sodium benzoate are examples of salts used as food preservatives. Sodium nitrite helps to preserve processed meat such as ham and sausages. Sodium benzoate is found in tomato sauce and chilli sauce.
