: Calculate The Oh And Ph Of A 0 0028 M Solution Of The Weak Acid Nitrous Acid Hno2 The Ka For The Nitrous Acid Is 8 1 (13.87 KiB) Viewed 37 times

Calculate the [OH] and pH of a 0.0028 M solution of the weak acid nitrous acid (HNO2). The Ka for the nitrous acid is 8.43 x 108 0 [OH] = 6.49 x 10-10 pH= 4.8 0 [ OH] = 4.78 x 10-12 pH= 9 0 [OH] = 1,3 x 10-5 pH= 8.2 O [OH] = 3.53 x 10-8 pH= 5.2
