Classify each aqueous solution as acidic, basic, or neutral at 25 °C. Acidic Basic Neutral pH = 7.00 Answer Bank -10 [H+) = 1.0 x 10-7 [OH) = 2.2 x 10-2 pH = 11.94 [H+] = 7.1 x 107 [OH)=1.6 x 10-9 [H+] = 1.8 x 10-4 pH = 3.88
Classify each aqueous solution as acidic, basic, or neutral at 25 °C. Acidic Basic Neutral pH = 7.00 pH = 2.17 [H+1 -1.0 x 10-7 [H+1 = 7.8 x 10-5 pH = 10.93 [OH-] - 5.2 x 10-12 [H+1=3.2 x 10-9 [OH-] = 3.0 x 10-5
