A: An acid is a chemical that gives off H +/10 -12 M, then [OH-] = 10 -2 M If [H+] = 10 -1 M, then [OH-] = 10 -13 M If [H+] = 10 -7 M, then [OH-] = 10 -7 M If [H+] = 1M, then [OH-] = 10 -14 M 1 x 24 = 24 2 x 12 = 24 3 x 8 = 24 4 x 6 = 24 6 x 4 = 24 SWBAT...... use the pH system to characterize acid, base, and salt/

4.The salt produced from a weak acid and a weak base may form an acidic, basic, or neutral solution. (You would have to compare the K a and K b values to determine whether or not the salt formed from a weak acid and base was acidic, basic, or neutral. We will not be doing that in this class.)
