#9 The next set of
questions involve determining the buffer capacity of the acetate/acetic acid buffer you o just made. Obtain 25.0 mL of your buffer in a beaker. Add 1.0 mL of 1.0 M HCl (or NaOH) and record the pH. 4.87 Submit Answer format: Number: Round to: 2 decimal places. #10 Obtain 25.0 mL of deionized water in a beaker. Add 1.0 mL of 1.0 M HCl (or NaOH) and record the pH. 1.41 Submit Answer format: Number: Round to: 2 decimal places, #11 Using equation 4, calculate the buffer capacity of the buffer acetic acid/sodium acetate solution= mol L-1 per unit pH change. Hints: See the buffer capacity formula#4 given in the background information, and note below the formula. Pay careful attention to units in the
question. Volume of buffer used is 0.025L. Moles of acid or base added to the buffer can be calculated using the molarity and volume of the HCI or NaOH added. Submit Answer format: Number: Round to: 2 decimal places.
