Carbonic and sulphuric acid are both acidic. However, they have different pH values. You are supplied with a 1.0 mol/dm3 solution of each. 1). Suggest a pH value for EACH solution. (2 marks) II). Explain the reason for the different pH values. (2 marks) i). State one way you could find out if your suggested pH values are accurate.

Explanation:
Suppose you had to work out the pH of 0.1 mol dm-3 hydrochloric acid. All you have to do is work out the concentration of the hydrogen ions in the solution, and then use your calculator to convert it to a pH.

Each mole of HCl reacts with the water to give 1 mole of hydrogen ions and 1 mole of chloride ions

My calculator wants me to enter 0.1, and then press the "log" button. Yours might want you to do it in a different order. You need to find out!
The pH of this acid is 1.
