Rank these items in order of decreasing acid strength. Acetic, Ka = 1.8 x 10-5 Phenol, Ka = 1.0 x 10-10 Hydrofluoric, pKa = 3.14 Benzoic, pKa = 4.20...

Rank these items in order of decreasing acid strength. Acetic, Ka = 1.8 x 10-5Phenol, Ka = 1.0 x 10-10Hydrofluoric, pKa = 3.14Benzoic, pKa = 4.20Nitrous, Ka = 4.5 x 10-4Note: A higher Ka means a stronger acid. To compare them, convert the pKa values to Ka using Ka = 10-pKa. Benzoic, Ka = 6.3 x 10-5, hydrofluoric, Ka = 7.2 x 10-4
