(i)Define buffer solutions.
(ii) State Lewis definition of acids and bases. Give one example of each.

Explain protonic concept of acids and base with one example each

Explain acid, base and salt. Give two examples in each case.

Give an example of acidic buffer.

Name the three states of matter. Give one example of each.

The nature of a solution whether neutral , acidic or basic depends upon its pH value. The pH of a solution changes when an acid or base added to it . Howerver the pH of the solution is maintained by the addition of a suitable buffer whether acidic or basic. (a) Define a buffer solution (b) Give one example each of acidic and basic buffers. (c) Define pH of a solution .
