4/10 HW – pH and pOH and Reverse

 

1.    Calculate the pH of each AND indicate if each is an acid or base.

       a.    [H3O+] = 1.4 x 10-3 M            

       b.    [H3O+] = 2.5 x 10-10 M           

       c.    [H3O+] = 6.1 x 10-4 M                   

d.    [OH-] = 3.5 x 10-2 M

e.               [OH-] = 8 x 10-11 M

f.                pOH = 10.5

 

2.    Calculate the [H3O+] and the [OH-] for each solution.

       a.    pH = 7.41

       b.    pH = 3.2

       c.    pOH = 5.0
