Question

Which pair of aqueous solutions can create a buffer solution if present in the appropriate concentrations?.

Answer 1

HF and NaF - If the right concentrations of aqueous solutions are present, they can produce a buffer solution.

What are buffer solutions and how do they differ?

• The two main categories of buffers are acidic buffer solutions and alkaline buffer solutions.
• Acidic buffers are solutions that contain a weak acid and one of its salts and have a pH below 7.
• For instance, a buffer solution with a pH of roughly 4.75 is made of acetic acid and sodium acetate.

Describe buffer solution via an example.

• When a weak acid or a weak base is applied in modest amounts, buffer solutions withstand the pH shift.
• A buffer made of a weak acid and its salt is an example.
• It is a solution of acetic acid and sodium acetate CH3COOH + CH3COONa.
