• When electric current is passed through water containing few drops of acid, What changes will you observe near the positive and negative electrode and What is your conclusion​ ?

$\underline{\underline{\sf{\maltese\:\:Answer}}}$

• When an electric current is passed through water containing few drops of acid, The acid breaks into its respective ions and migrate towards the positive and negative electrode

$\underline{\underline{\sf{\maltese\:\:Explanation}}}$

For Example : Hydrochloric acid in solution dissociates into hydrogen ions and chloride ions. $\sf{HCl \to H^+ + C^{-}}$

The H⁺ ions are attracted to the negative electrode and Cl⁻ ions are attracted to the positive electrode. The ions are neutralized at their respective electrodes. $\sf{Cl \to Cl + e^-}$ and $\sf{H^+ + e^-\to H}$

The net result of passing electric current is :

$\bf{HCl \to H_{2}+Cl_{2}}$

So, Cl₂ is liberated at the positive electrode and H₂ is liberated at the negative electrode. Thus, we can see the formation of gases near the positive and negative electrodes.

Therefore

• When an electric current is passed through water containing few drops of acid, The acid breaks into its respective ions and migrate towards the positive and negative electrode
