Problem Details

Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. What is the molar concentration of H3O+ in a cola that has a pH of 4.240? 

Express your answer with the appropriate units. 





Rank the following from most to least acidic. Rank from most to least acidic. To rank items as equivalent, overlap them.

[H3O+] = 10-2               [H3O+] = 10-6            pH = 14          pH = 3                pH = 5
