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 pH if the hydrogen ion concentration is 1 x 10-1

Answer 1

Please help!!!

Answer 2

Since pH=-logx, if x is a power of 10, then the pH is just the negative of the 10's exponent.

If your H+ concentration is 10^(-12), the pH is 12, and the solution is basic.
If your H+ concentration is 10^(-7), the pH is 7 and the solution is neutral.
If your H+ concentration is 10^(-1), the pH is 1 and the solution is acidic.

Does that make sense?
