Calculate the pH of a solution that is prepared by dissolving 0.297 mol of pentafluorobenzoic acid (CF.COOH, K, -3.30x10-2) and 0.650 mol of hydrocyanic acid (HCN, K, = 6.17x10-10) in water and diluting to 5.90 L. Also, calculate the equilibrium concentrations of C F COOH, C F C00", HCN, and CN. Do not make an approximation unless the initial acid concentration is greater than 1000 × K. (Hint: The pH will be determined by the stronger acid of this pair.)...

A stock solution was prepared by dissolving 0.593 g of pure ASA (molar mass = 180.2 g/mol) with NaOH solution and diluting with water in a 1000 mL volumetric flask. This was followed by pipetting 4.00 mL of the stock solution into flask A and 5.0 mL of the stock into flask B. Flasks A and B were each diluted to 20 mL mark of the volumetric flask. What are the concentrations, in molarity, of ASA in flasks A and...
