Expert Solution
Step 1:

Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and specify the other subparts (up to 3) you’d like to get answered.

A solution is said to be acidic, when the pH of the solution is less than 7 and it donates protons to the solution.

A solution is said to be basic, when the pH of the solution is more than 7 and it accepts protons from the solution.

A solution is said to be neutral, when the pH of the solution is equal to 7 and it accepts and donates equal amount of protons in the solution.

An acidic buffer is defined as an aqueous solution that consists of a mixture of a weak acid and its conjugate base.

A basic buffer is defined as an aqueous solution that consists of a mixture of a weak base and its conjugate acid.

The pH of the buffer solution changes to a very little amount when a small quantity of strong base or acid is added to it.
