Q

pH and H+ relationships

A
  • expresses H+ concentration as the negative logarithm of the H+ concentration in moles per liter
  • pH = -log[H+]
  • [H+] = 10^-pH
2
Q

what is the pH of a 6.7*10^-3 M H+ solution?

A
  • pH = -log[H+]
  • pH = -log[6.7*10^-3]
  • pH = 2.16
3
Q

what is the [H+] if the pH of a solution is 4.50?

A
  • [H+] = 10^-pH
  • [H+] = 10^-4.5
  • [H+] = 3.2*10^-5
