25.Which of the following statement(s) is/are correct about the ionic product of water? A) K_(i) "(ionization constant of water) " B) pK_(i) > pK_(W) C) At 25^(@)C , K_(i) = 1.8times10^(-14) D) lonic product of water at 10^(@)C is 10^(-14)

if ionic product of water is K_w=10^(-16) at 4^@C , then a solution with pH =7.5 at 4^@C will

The dissociation of weak electrolyte (a weak base or weak acid) is expressed in terms of Ostwald's dilution law. An acid is substance which furnishes a proton or accepts an electron pair, where a base is proton acceptor or electron pair donor. Stronger is acid, weaker is its conjugate base. The dissociation constants of an acid (K_(a)) and its conjugate base (K_(b)) are related by K_(w)=K_(a)xxK_(b) , where K_(w) is ionic product of water equal to 10^(-14) at 25^(@)C . The numerical value of K_(w) however increase with temperature. In a solution of an acid or base [H^(+)][OH^(-)]=10^(-14) . Thus the [H^(+)] in a solution is expressed as: [H^(+)]=10^(-pH) and pH+pOH=14 . Buffer solution are the solutions which do not show appreciable change in the pH on addition of small amount of acid or base. Which of the following statements are wrong ? (1) Increase in temperature has no effect on neutral nature of water. (2) Increase in temperature of pure water decreases its pH. (3) Increase in temperature of pure water decreases its autoprolysis. (4) Increase in temperature of pure increase its ionic product. (5) Increase in temperature of pure water decreaseas degree of dissociation of water.

27.Which of the following expressions is/are true ? A) [H^(+)] = [OH^(-)] = sqrt(K_(w)) for a neutral solution B) [OH^(-)] C) "pH+pOH=14" at all temperature D) OH^(-) = 10^(-7) M for a neutral solution at 25^(@)C
