Imagine that a 50.0 mM MES buffer is made by dissolving an appropriate mass of solid MES in water, adding NaOH ("titrating") until 60.0% of the MES is converted to its conjugate base, then diluting to the required final volume Write the net ionic equation for the reaction that occurs when a little HCl is added to this buffer, then calculate the pH that results when 1.00 mL of 0.250 M HCI is added to 50.0 mL of buffer Calculate the pH that results when 1.00 mL of 0.250 M NaOH is added to 50.0 mL of this buffer. Why does the pH change more when you add NaOH then when you add the same amount of HCI? Calculate the pH that results when 5.00 mL of 0.250 M NaOH is added to 50.0 mL of this buffer.

In the titration of 25.0 mL of 0.1 M CH3COOH with 0.1 M NaOH, how is the pH calculated before the titrant is added? Group of answer choices The pH is based on the concentration of protons present in the solution, which is equal to the original concentration of the acid. The pH is calculated using the H-H equation for a buffer solution, using the ratio of the concentrations of the base and the acid, and the pKa of the acid. The pH is 7. The pH is calculated by determining the concentration of weak conjugate base present in the solution, using an ICE table to calculate the hydroxide ion concentration present after hydrolysis, subtracting pOH from 14, and taking the negative log of the result. The pH is calculated by determining the concentration of excess hydroxide ions in the solution, subtracting pOH from 14, and taking the negative log of the result.

Buffer capacity is a measure of a buffer solution's resistance to changes in pH as strong acid or base is added. Suppose that you have 105 mL of a buffer that is 0.260 M in both benzoic acid (CH₂COOH) and its conjugate base (CH₂COO¯). Calculate the maximum volume of 0.270M HCl that can be added to the buffer before its buffering capacity is lost. volume: mL
