Question

2) What is the chemical formula of rust?

3) Write down the chemical formula of hydrated copper sulphate​

Answer 1

Explanation:

2)It is estimated that about one-seventh of all iron production goes to replace the metal lost to corrosion. Rust is apparently a hydrated form of iron(III)oxide. The formula is approximately Fe2O3•32H2O, although the exact amount of water is variable.

3)Hydrated Copper sulphate⇒CuSO4.5H2O

Anhydrous Copper Sulphate⇒CuSO4

Activity to show they are interconvertible:

(Blue)CuSO4.5H2OH2O⇌△(White)CuSO4

When hydrated CuSO4 is heated in boiling tube, the water of crystallization is lost. The salt turns white.

However, again when crystals are moistened with water the blue color reappears. This is how they are interconvertible.

Answer 2

• Rust is hydrated ferric oxide and its chemical formula is Fe2O3. xH2O.
• Hydrated copper sulphate- CuSO4 .
