(i) Giving reason for each. State which of the following will conduct electricity and which will not?
(a) A solution of glucose
(b) Dil. Hydrochloric acid
(iii) If acetic acid and hydrochloric acid of same concentration are taken, which of the two is a stronger acid and why?
(iii) How is the strength of an acid affected when some water is added to it?

Explanation

(i) (a) Solution of glucose will not conduct electricity because it does not have ions.
(b) Dil. HCl will conduct electricity because it produces `H^+` ions in water.
(ii) HCl is stronger because it gives more `H^+` ions than acetic acid.
(iii) The strength of the acid decreases.
