Determine the amount of water that must be added to a 2-litre solution of sulphuric acid to dilute it from a ph of 2.7 to a ph of 3.
Answers: 2
![pH = -log[H^+]](/tpl/images/0231/3458/7d119.png)
![[H^+] = 10^{-pH}\ M](/tpl/images/0231/3458/eadf1.png)
![[H^+] = 10^{-2.7} = 0.001995\ M = 0.002\ M](/tpl/images/0231/3458/2c294.png)
![[H^+] = 10^{-3} = 0.001\ M](/tpl/images/0231/3458/a8530.png)
