A student wanted to prepare carbon(iv) oxide gas by reacting dilute sulphuric (VI) acid with barium carbonate .State and explain the observation made

In this reaction, when dilute sulphuric acid reacts with barium carbonate, carbon dioxide gas (CO2) is produced. The observations made during this reaction are as follows:

1. Effervescence: Upon mixing the dilute sulphuric acid with barium carbonate, you will notice the formation of bubbles or effervescence. This is an indication that a gas is being released during the reaction.

2. Formation of a white precipitate: As the reaction progresses, a white precipitate, which is barium sulphate (BaSO4), is formed. This is due to the reaction between barium carbonate and sulphuric acid, resulting in the formation of insoluble barium sulphate.

The overall balanced equation for this reaction is:

H2SO4 + BaCO3 → BaSO4 + CO2 + H2O

So, the main observation is the effervescence of a gas (CO2) and the formation of a white precipitate (BaSO4) during the reaction.
