Examples of efflorescence compound

Answer 1

1. Sodium carbonate (soda ash) forms efflorescence when exposed to air, causing a white powdery substance to form on the surface.

2. Calcium sulfate (gypsum) can also form efflorescence when exposed to moisture, resulting in a white crystalline residue on the surface.

3. Potassium nitrate (saltpeter) is known to produce efflorescence in certain environmental conditions, leaving a white or yellowish powder behind.

4. Magnesium sulfate (Epsom salt) can create efflorescence when dissolved in water and allowed to dry, forming white crystals on the surface.

5. Borax, a naturally occurring mineral compound, can form efflorescence when mixed with water and left to evaporate, leaving a white powdery residue behind.
