Explain why : (a) anhydrous HCl is a poor conductor while aqueous HCl

1.	Explain why : (a) anhydrous HCl is a poor conductor while aqueous HCl is an excellent conductor. (b) when the stopper of a bottle full of hydrogen chloride gas is opened there are fumes in the air. (c) a solution of hydrogen chloride in water turns blue litmus red and conducts electricity, while a solution of the same gas in toluene : (i) has no effect on litmus, and (ii) does not conduct electricity. (d) thick white fumes are formed when a glass rod dipped in NH4OH is brought near the mouth of a bottle full of HCl gas. (e) dry hydrogen chloride gas does not affect a dry strip of blue litmus paper but it turns red in the presence of a drop of water. (f) hydrogen chloride gas is not collected over water.
