Question

(i) Processing of dilute sulfuric acid with granular zinc. (ii) Processing dilute hydrochloric acid with a magnesium strip. (iii) Processing of dilute sulfuric acid with magnesium strip. (iv) Processing of dilute hydrochloric acid with iron ore. Please give me answer​

Answer 1

Explanation:

I . When dilute sulphuric acid is poured on zinc granules, then zinc being more reactive than hydrogen displaces it from the acid and forms zinc sulphate and hydrogen gas.

ii .When a piece of magnesium strip is dropped in dilute hydrochloric acid, a new product hydrogen gas is evolved and Magnesium chloride has properties different from that of magnesium, which is irreversible and hence, it's a chemical change.

iii . Magnesium reacts with dilute sulphuric acid to form magnesium sulphate and hydrogen gas. This is a single displacement reaction and also exothermic.

iv . When dilute Hydrochloric acid is added to iron filings, iron(II) chloride & hydrogen gas is produced. In this reaction iron displaces hydrogen from hydrochloric acid to form iron chloride & hydrogen gas this reaction is a single displacement reaction.
