- Nitric acid (HNO3) is a strong acid that completely ionizes when dissolved in water (pKa = -1.30). Calculate the pH of 10 mg/L HNO3. a. Unlike nitric acid, butyric acid (CH3CH2CH2COOH) is a weak acid (pKa = 4.8). Calculate the pH of a solution when 90% of the CH3CH2CH2COOH is dissociated. b. Briefly explain how you can use the pKa values of these two molecules to determine that nitric acid is a strong acid, while butyric acid is a weak acid.Based on the following samples, which have positive result with iodoform test?
