Statement-1: Aqueous solution of ammonium carbonate is basic. Statement-2: Acidic/basic nature of a salt solution of a salt of weak acid and weak base depends on K_(a) and K_(b) value of the acid and the base forming it.

The sum of pH and pK_(b) for a basic buffer solution is 13. The ratio of the concentration of the base to that of the salt is

Number of statement(s) that is/are correct : (a) On increasing temperature, pH of pure water decreases On increasing temperature, pOH of pure water decreases (c) On increasing dilution, dissociation of weak electrolyte increases (d) pH of 10^(-7) M NaOH (aq) is 7 at 25^(@)C . (e) At equivalence point (during titration of acid ad base) solution must be neutral. (f) Generally, pH of buffer solution does not change on dilution. (g) pH of salt of weak acid and weak base depends on concentration of salt.

What are buffer solutions ? How do they act ? Explain the buffer action of (i)an acidic buffer (ii) a basic buffer

In a buffer solution consisting of a mixture of weak base and its salt, the ratio of salt to base is increases 10 times , the pOH of the solution will

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. (i) Define a buffer solution (ii) Give one example each of acidic and basic buffers. (iii) What is the value associated with the use of buffer solution in human beings ?
