Answer 1

Answer:option 2nd

Explanation:when hcl is added some free ions (H+ And SO42-) are present,, similarly in H2SO4 and lemon juice (weak acid)

Answer 2

Answer:

2.1 , 2 ,4

Explanation:

Lemon juice conducts electricity because it contains citric acid.Citric acid breaks into charged actions and anions when dissolved in water.They conduct electricity because the charged particles are able to flow within the acid.

Sulphuric acid when dissolved in water ionises into hydroxonium and sulphate ions.These ions moves to the oppositely charged electrodes hence conduct electricity

Hydrochloric acid when dissolved in water ionises into active anions and actions which move to oppositely charged electrodes and conduct electricity.
