A buffer is a solution that is a mixture of either a weak acid and its conjugate base or a weak base and its conjugate acid. When strong acids or strong bases are added, buffers either accept protons when they are in excess or donate protons when they have been depleted to minimize changes in pH. Which of the statements correctly describe the properties of a buffer? Select one or more: a. The weak base of an alkaline buffer will...

The cytoplasm of most cells is buffered by the combination of bicarbonate (HCO3-, the weak acid) and carbonate (CO32-, the conjugate base) ions that buffer the cell at a pH of around 7.8. Would you expect the presence of other ions that are normally present in the cell (other than H+) have any effect on the ability of carbonate and bicarbonate ions to buffer the cell? Explain your answer.

What reaction that occurs when HCl is added to a buffer solution composed of HC2H3O2 and NaC2H3O2. What reaction that occurs when is added to a buffer solution composed of and . As HCl (H− and Cl+) is added, the H− will pair with C2H3O−2, neutralizing the acetate ion and becoming acetic acid. As HCl (H+ and Cl−) is added, the H+ will pair with HC2H3O2, neutralizing the acetate ion and becoming an acetic base., As HCl (H+ and Cl−) is added,...

1. A 0.100 M solution of the weak acid HB has a pH of 3.00. What are the [H+], [B-], and Ka for this acid? 2. A solid acid is dissolved in water. Half the solution is titrated to a phenolphthalein end point with NaOH solution. The neutralized and acid solutions are then mixed and the pH of the resulting solution is found to be 4.60. Find Ka of the solid acid. 3. Assuming your buffered solution contains acetic acid,...

A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 mL solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O,. The initial concentration of both the acid and the base are 0.0100 mol/ 0.1000 L...

Which of the following is true for a buffered solution? The solution resists change its [H^+] The solution will not change its pH very even if a concentrated acid is added. The solution will not change its pH very much even if a strong base is added. Any H^+ ions will react with a conjugate base of a weak acid already in solution. All of these
