The pH of a 1.50 M solution of HClO is 3.67. a. Calculate the Ka of HClO. (6 pts)
1)Which expression is the correct form of the Henderson-Hasselbalch equation? pH = pKa + log([base]/[acid]) pKa = pH + log([base]/[acid]) pH = pKa − log([base]/[acid]) pH = pKa + log([acid]/[base]) 2) Use the Henderson-Hasselbalch equation to calculate the pH of a buffer solution prepared by mixing equal volumes of 0.220 M NaHCO3 and 9.00×10−2 M Na2CO3. (Ka values are given in Appendix C.) Express your answer using three significant figures.
17.a) Calculate the pH of a 500 mL solution that is 0.185 M in HClO and 0.200 M in NaClO. (HClO, Ka = 3.8 x 10-8 ) b) Calculate the pH after 0.005 mol of KOH has been added to the solution. c) Calculate the pH after 0.005 mol of HCl has been added to the solution.
Calculate the pH for 0.50 M solution of the salt NaClO. The Ka for HClO is 3.0x10^-8
Ka for hypochlorous acid, HClO, is 3.0 x 10^-8. Calculate the pH after 10.0, 20.0, 30.0, and 40.0 ml of 0.100M NaOH have been added to 40.0ml of 0.100M HClO.

The pH of a buffer is calculated by using the Henderson-Hasselbalch equation: pH=pKa +log[Base]/[Acid] Part A: What is the pH of a buffer prepared by adding 0.809mol of the weak acid HA to 0.406mol of NaA in 2.00 L of solution? The dissociation constant Ka of HA is 5.66
HClO is a weak acid (Ka=4.0×10−8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.014 M in NaClO at 25 °C?
What is the pH of a 0.10 M NaClO solution if Ka for HClO is 3.0 x 10^-8?
