1.
When clean air is bubbled through pure water,
the pH of the water changes gradually. Why
do you think this is so?

Answer 1

Answer:

The pH value of water could dropped due to a reversible reaction between water and carbondioxide which leads to formation of carbonic acid. Carbondioxide gas is responsible for change in pH.

please follow and make me brainalist

Answer 2

Answer:

yes

Explanation:

the pH value of water could dropped due to a reversible reaction between water and carbon dioxide which leads to formation of carbonic acid.carbondioxide gas is responsible for the change in PH.so,more the presence of CO2 in air,more the drop in PH value of water air bubble.

hope it helps
