Question

Identify the acid and base which form sodium hydrogen carbonate.Write chemical equation in support of your answer.State whether this compound is acidic,basic or neutral.also write its pH value.

Answer 1

Hello!

Answer:

NaOH is Base and H2CO3 (Both 2 and 3 in subscript) is Acid

NaOH + H2CO3 → NaHCO3 + H2O

The compound is basic as in the reaction a strong base NaOH is reacted with a weak acid H2CO3.

pH is more than 7!!!

Hopefully it will help you! ❤️

Answer 2

Let us consider a strong base 'Sodium Hydroxide' and weak acid 'Hydrogen Carbonate' to react.

$\mathrm{NaOH}+\mathrm{H}_{2} \mathrm{CO}_{3} \rightarrow \mathrm{NaHCO}_{3}+\mathrm{H}_{2} \mathrm{O}$

After the reaction, the resultant compound is Sodium Bicarbonate and water.

The product is known as Baking soda which is used in cooking and is basic in nature because it weakly ionizes in water. The pH value with be more than 7.

One more example from strong acid Hydrochloric acid and neutral Sodium carbonate as follows:

$H C l+N a_{2} C O_{3} \rightarrow N a H C O_{3}+H C l$

The resultant compound is an acidic salt with Ph value greater than 7.
