Given a 1.00 L solution that is 0.60 M HF and 1.00 M KF, calculate the pH after 0.060 mol NaOH is added, and calculate the pH after 0.20 mol HCl is added to the original solution. Ka = 7.2x10-4 pH = when NaOH is added pH = when HCl is added
Hi, I need help with this question, thanks! What is the molarity of the initial HCl solution of 45.78 mL of 0.50 M HCl after adding 30.3 mL of deionized water? A student was conducting a titration experiment and was asked to calculate the theoretical pH of the solution at various points in the titration curve. In this experiment, the student added 45.78 ml of a 0.50 M solution of HCI to a 200 ml beaker. The student then added...
