Question

an Apparatus has been set up state the observation made when electric current is passed through the solution in the beaker if the solution is replaced by glucose solution what will be the observation on passing electric current give reason for your observations in each case​

Answer 1

Answer:

The bulb glows in the rst case when an aqueous solution of HCl is taken because in this solution HCl

being strong acid is completely ionised to give H and Cl ions . Due to the presence of ions the aqueous

solution becomes conducting and the circuit is completed.

In case of Aqueous solution of glucose , glucose is a carbohydrate and a covalent compound which does

not ionise. Therefor glucose solution is non conducting and bulb does not glow.

Yes the bulb does glow if the experiment is repeated with aqueous solution of NaOH and NaCl. Because

both of these dissociate into ions when dissolved or when aqueous solution is prepared. NaOH ionises into

Na and OH and NaCl ionises into Na and Cl .
