Aquenous solution of which of the following compounds is the best conductor of electric current ?

Answer»

Ammonia, `NH_(3)`
Fructose, `C_(6)H_(12)O_(6)`
Acetic acid, `C_(2)H_(4)O_(2)`
HYDROCHLORIC acid HCl

Solution :Fructose is a non-electrolyte, `NH_(4)OH` and `CH_(3)COOH` are weak electrolytes, HCI is a strong electrolyte. Hence, HCI dissociates completely in aqueous solution and, therefore is the best CONDUCTOR of electricity .
