A buffer is prepared by adding 20.0 g of sodium acetate (CH3COONa) to 510 mL of a 0.145 M acetic acid (CH3COOH) solution. 1. Determine the pH of the buffer. Express your answer using two decimal places. 2. Write the complete ionic equation for the reaction that occurs when a few drops of hydrochloric acid are added to the buffer. Express your answer as a chemical equation. Identify all of the phases in your answer. 3. Write the complete ionic equation for the reaction that occurs when a few drops of sodium hydroxide solution are added to the buffer. Express your answer as a chemical equation. Identify all of the phases in your answer.
A buffer is prepared by adding $20.0 \mathrm{~g}$ of acetic acid $\left(\mathrm{CH}_{3} \mathrm{COOH}\right)$ and $20.0 \mathrm{~g}$ of sodium acetate $\left(\mathrm{CH}_{3} \mathrm{COONa}\right)$ to enough water to form $2.00 \mathrm{~L}$ of solution. (a) Determine the $\mathrm{pH}$ of the buffer. (b) Write the complete ionic equation for the reaction that occurs when a few drops of hydrochloric acid are added to the buffer. (c) Write the complete ionic equation for the reaction that occurs when a few drops of sodium hydroxide solution are added to the buffer.
