Question

Which 3 chemical substances are obtained when electricity is passed by an aqua solution of brine?

Answer 1

$\boxed{\mathbb{BRINE}}$

The Aqueous solution of Sodium Chloride (NaCl) is called as Brine.

When electrolysis is carried out using Brine we obtain Three products.

The products include the following :-

$\begin{aligned} 1.Sodium Hydroxide(NaOH) \\ 2.Hydrogen (at\:cathode) \\ 3. Chlorine (at\:anode) \end{aligned}$

$\rule{200}{2}$

This process is commonly called as $\bold{\sf{Chlor-alkali\:process}}$

This is because the reaction leads to the formation of an alkali that is NaOH and Chlorine gas.

The reaction carried out is as follows :-

$\begin{aligned} NaCl(aq) +H_{2}O(l) \xrightarrow{electrolysis} NaOH+\\H_{2}(\uparrow) +Cl_{2}(\uparrow) \end{aligned}$

$\rule{200}{2}$

Hydrogen gas is liberated at the cathode because Hydrogen is positively charged and cathode is negatively charged


Chlorine is liberated at Anode because Chlorine is negatively charged while Anode is positively charged
