Question

How the pH value of the solution is changed when CO2 gas is passed through pure water

Answer 1

Hey


When CO2 ( carbon dioxide ) is passed through H2O ( water ) , then it reacts with water to form H2CO3 ( Carbonic acid ) .


We know that ,

acid reduces the value of pH .

So ,

pH will be less than 7 in this case .


thanks :)

Answer 2

Hey


pH will be less than 7 .


Reason :-

When carbon dioxide gets mixed up with the water then it results in the formation of "carbonic acid " .

And we know that ,

the pH of acids are less than 7 .


thanks ^_^
