Can anyone explain specifically how water concentration affects carbon dioxide levels and pH?

The amount of CO2 is proportional to the increase of acidity in water.
That is, the more CO2 in the water, more acidic the solution becomes and the lower the pH
That is because CO2 dissolves in water to produce carbonic acid which increasing the pH
In terms of this biologically, the blood is subjected to chances in it's composition, including the addition of acidic substances (such as CO2). The body then has to use homeostasis to counteract the increase in acidity of the blood.
This is achieved through buffers in the blood.

The higher the water concentration, the more CO2 that can dissolve in the water. As stated by Rifipi, the amount of c02 that can dissolve in water is proportional to the amount of water. Thus you get more carbonic acid forming. Through the reaction between c02 + h20 <--> H2c03. H2c03 dissociates into 2H+ + co-3. The 2h+ increases acidity, as ph is dependent on the concentration of hydrogen ions in solution.
