Question

identify the incorrect pair 1. quick lime - calcium hydroxide 2. lemon- acidic acid 3. tamarind - tartaric acid 4. yoghurt- lactic acid

Answer 1

quick lime - calcium hydroxide is the incorrect pair.

Quicklime or lime is an inorganic material known as Calcium oxide (CaO).Calcium carbonate or limestone, also known as chalk is subjected to calcination which forms quicklime (CaO).

Upon subsequent addition of water, hydrated lime or slaked lime is formed which is called as Calcium Hydroxide (CaOH2)

Answer 2

" 1 "

Lemon is acid

Quick lime is calcium oxide.

Tamarind have actually the tartaric acid.

Yoghurt is actually the curd so it has lactic acid.
