The mixture of 100.0 mL of 0.100 M NaOH (aq) and 100.0 mL of 0.300 M CH3COOH (aq) will result in a buffer. (a) Explain why the resulting solution is a buffer. (b) What is the pH of this buffer?

1) Calculate the pH of a solution prepared by dissolving 1.60 g of sodium acetate, CHCOONA, in 64.0 ml of 0.20 Macetic acid, CH,COOH(aq). Assume the volume change upon dissolving the sodium acetate is negligible. K, of CH3COOH is 1.75 x 10

Which statement describes the action of a buffer composed of acetic acid (CH3COOH) and sodium acetate (NaCH3COO)? How does a buffer resist change in pH upon addition of a strong acid? By titration, it is found that 73.3 mL of 0.189 M NaOH(aq) is needed to neutralize 25.0 mL of HCl(aq). Calculate the concentration of the HCl solution.

Calculate the change in pH when 5.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq). A list of ionization constants can be found here.   B)Calculate the change in pH when 5.00 mL of 0.100 M NaOH(aq) is added to the original buffer solution.

A buffer is made by adding 0.500 mol CH3COOH and 0.500 mol CH3COONa to enough water to make 1.000 L of solution. The pH of the buffer is 4.84. Calculate the pH of this solution after 5.0 mL of 4.0 M NaOH (aq) solution is added

A mixture is made using 50.00mL of 0.20mol L-1 NaOH(aq) and 50.00mL of distilled water. What is the pH of this solution?
