Question

Soda Water Has A pH Value Of _______

Answer 1

Soda water:

• Soda water contains carbon dioxide dissolved in water at high pressure.
• So, carbon dioxide reacts with water to form weak carbonic acid.

$\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}+\underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}\rightleftharpoons \underset{\mathrm{Carbonic}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)}$

• Due to the presence of dibasic acid, the pH of soda water is acidic in nature.

Therefore, Soda water has A pH value of 3 to 4
