Extracted text: What are the molar concentrations of acetic acid (CH3COOH)(CH3COOH) and sodium acetate (CH3COONA)(CH3COONA) in an aqueous solution buffered at a pH of 4.204.20 that has a freezing point of -3.62 °C?-3.62 °C? Assume complete dissociation of sodium acetate and a density of 1.02 g/mL for the solution. The pКapКa for СНЗСООНСНЗСООН is 4.75.
