Answer 2

The chemical formula of Indian saltpetre is KNO3.

• The chemical name of KNO3 is potassium nitrate.
• It is an ionic compound or a salt as it contains K+ and NO3- ions.
• It is colourless and odourless.
• It is soluble in glycerol and ammonia but partially soluble in ethanol.
• It is an oxidant and hazardous chemical. so, should be handled and used carefully.
• It is non-flammable.
• The crystal structure of KNO3 is orthorhombic.
• The crystal structure of KNO3 is orthorhombic.
• It is a nitrogen containing compound that is used extensively as crude salt in India which is why it is known as Indian saltpetre.
