477.1 mg of KHP is dissolved in approximately 50 mL of de-ionized water in a 250 mL Erlymeyer flask and titrated with an NaOH solution. The titration required 25.31 mL to reach the phenolphthalein endpoint. The NaOH solution was also used to titrate 25.00 mL of a dilute HCl solution. The dilute HCl solution required 27.73 mL to reach the phenolphthalein endpoint. Determine the concentrations of the NaOH and the HCl solutions.
