Question 3 options:

When CO2 increases, pH increases and acidity decreases.


When CO2 increases, pH decreases and acidity increases.


When CO2 increases, pH decreases and acidity decreases.


There is no relationship between CO2 and pH

Answer 1

The answer is When CO2 increases, pH decreases and acidity increases.

Step-by-step explanation:

Excess carbon dioxide (CO2) in the atmosphere gets absorbed at the ocean surface of the ocean. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
