Problem

Calculate the [H+] of each of the following solutions at 25ºC. Identify each solution as neutral, acidic, or basic.

a. [OH -] = 1.5 M

Solution

The relationship between [H+] and [OH-]:


Kw=H+OH-

Kw = autoionization constant of water

Kw = 1.0x10-14 at T = 25°C


Recall that:

  • [OH-] > [H+] basic
  • [H+] > [OH-acidic
