Use the data in the tables below to label the stronger acid in each pair Which acid in each pair has th stronger conjugate base a H O or HSO b HNO or HI 0 e HBr or HCI is the stronger acid Increasing acid strength is the stronger acid Increasing acidity is the stronger acid Table 9 2 Relative Strength of Acids and Their Conjugate Bases Conjugate Base Strong Acids Hydrolodic acid Hydrobromic acid Hydrochloric acid Sulfuric acid Nitric acid Acid Hydronium ion Weak Acids Phosphoric acid Hydrofluoric acid Acetic acid Carbonic acid Ammonium ion Hydrocyanic acid Water HI HBr HCI H SO HNO H O Hydrogen sulfate ion Phosphoric acid Hydrofluoric acid H PO HF CH COOH H C NH HCN H O has the stronger conjugate base has the stronger conjugate base Acetic acid Carbonic acid Dihydrogen phosphate ion Ammonium ion Hydrocyanic acid Bicarbonate ion Hydrogen phosphate ion has the stronger conjugate base IT Br CI HSO NO H O H PO F CH COO HCO NH CN OH Table 9 3 Acid Dissociation Constants K for Common Weak Acids Acid K 1 2 x 10 7 5 x 109 Structure HSO H PO HF lodide ion Bromide ion Chloride ion Hydrogen sulfate ion Nitrate ion CH COOH H C H PO NH HCN HCO HPO Water Dihydrogen phosphate ion Fluoride ion Acetate lon Bicarbonate ion Ammonia Cyanide ion Hydroxide ion 7 2 x 10 1 8 x 10 4 3 x 10 6 2 x 10 5 6 x 10 4 9 x 10 5 6 x 10 2 2 x 10 2 increasing base strength
