Question

The pH of a solution ranges from 0 to 14. An acid has a pH less than 7. Pure water is neutral and has a pH of 7. The pH of a solution is given by pH = -logx where x represents the concentration of the hydrogen ions in the solution in moles per liter. Find the hydrogen ion concentration of the pH=5.4

Answer 1

Answer:The easiest way to do this is to just raise 10 to the negative value of the pH. Thus, in this case hydrogen ion concentration would be 1x10-2.4. However, one doesn't usually leave it that way, so you put it in to the more conventional form as

3.98x10-3 and this would be the hydrogen ion concentration. If you take the negative log of this number (pH) you will get 2.4
