If concentration of two weak bases are same and D.O.D `(alpha)` are very less their ralative strength can be compared by :

A

`([H^(+)]_(1))/([H^(+)]_(2))`

B

`(alpha1)/(alpha2)`

C

`(C_(1)alpha_(1))/(C_(2)alpha_(2))`

D

`(K_(a1)C_(1))/(K_(a2)C_(2))`

A parallel plate capacitor has plates of area A separated by distance ‘d’ between them. It is filled with a dielectric which has dielectric constant that varies as K (y) = k _(0) (1+ alpha y) where ‘y’ is the vertical distance measured from base of the plates. The total capacitance of the system is best given by: (K _(0) is constant)

Solution of a weak acid and its anion (that is,its conjugate base) or of a base and its common cation are buffered. When we add a small amount of acid or base to any one of the, the pH of solution change very little. pH of buffer solution can be computed as for acidic buffer : pH=pK_(a)+ log.(["Conjugate base"])/(["Acid"]) for basic buffer : pOH=pK_(b)+log.(["Conjugate acid"])/([Base]) It is generly accepted that a has useful buffer cpacity (pH change resisting power) provided that the value of [salt or conjugate base] /[acid] for acidic buffer lies within the range of 1 : 10 to 1. Buffer capacity is maximum when [conjugate base] = [acid] Useful buffer range of weak acid HA(K_(a)=10^(-5)) is :

Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: (a) Both A and R are true and R is the correct explanation of A. (b) Both A and R are true but R is NOT the correct explanation of A. (c) A is true but R is false. (d) A is false and R is also false. Assertion: The whole mass of the atom is concentrated in the nucleus. Reason: The mass of the nucleus can be either less or more than the sum of the masses of nucleus.
