in a buffer solution of 1 L ,THERE ARE 0.1 mole CH3COOH and 0.005 mole CH3COONa .in this solution 0.08g NaOH is mixed. what is the pH of the solution after mixing base?
show the procedure

30 cm^3 0.05 M Ca(OH)2 and 100 cm^3 0.1 M CH3COOH are mixed.what is the pH of this buffer solution?? [K of CH3COOH=1.8*10^-5]
show the procedure

The dissociation equilibrium of a gas AB2 can be represented as
2AB2(g)=2AB(g)+B2(g)
The degree of dissociation is 'x' and it is small as compared to 1. The expression relating the degree of dissociation (x) with equilibrium constant Kp and total pressure P is
(1)2Kp/P
(2)2Kp/P^1/3
(3)2Kp/P^1/2
(4)Kp/P
