18). The formulas and the structures of two acids are shown below. Which acid is a stronger acid? If the acid strength of the two acids is equal, say so. Cl2CHCOOH CH3COOH но но CI-C-C-OH н-с-с-он ČI Ką = 0.0324 Ką = 1.82 x 10-5 %3D a. Cl¿CHCOOH is a stronger acid than CH;COOH. b. CH;COOH is a stronger acid than CI½CHCOOH c. The two have equal acid strength. d. none of the above

What is the concentration of OH- in 0.1863 M HNO2 ? See reaction belowHNO2 + H2O ↔ NO-2 + H3O+ Ka = 4.600x10-4

Solve the whole question. Also the column for relative strength shows 1 being the strongest, 2 then 3 being the weakest so rank them.
