Read the following passage and answer the questions at the end of it. Conductivity of silicon increases if it is doped with certain other elements. Doping means introduction of small amount of impurities like phosphorus, arsenic or boron in the pure crystal. In pure silicon four valencies are used in bonding with other four adjacent silicon atoms. When a silicon crystal is doped with a group - 15 element (with five valence electrons) such as P, AsSb or Bi, the structure of the crystal lattice remains unchanged. Out of the five valence electrons of group - 15 doped element, four electrons are used in normal covalent bonding with silicon and fifth electron is delocalised and thus conducts electricity Doping a silicon crystal with a group-13 element (with three valence electron) such as B, Al, Ga or In produces a semiconductor with three electrons in dopant. The place where fourth electron is missing is called as electron vacancy or hole. Silicon that has been doped with group - 15 elements is called

Higher the amount of acid or base used to produce a definite change of pH in a buffer solution,higher will be its buffer capacity. Buffer capacity of solution is maximum under the following conditions: [Salt= [Acid] (in acid buffer), [Salt] = [Base] (in base buffer) pH of a buffer solution lies in the range given below: pH = pk_(a)pm1 , In other words, any buffer solution can be used as buffer up to two pH units only, depending upon the value of pK_(a) , or pK_(b) ,. A buffer is said to be efficient when pH_(a) =pK_(a) , or pOH= pk_(b) Which among the following solution will be the most efficient buffer?

Higher the amount of acid or base used to produce a definite change of pH in a buffer solutions, higher will be its buffer capacity . Buffer capacity of solution is maximum under the following conditions: [Salt ]= [Acid ](in acid buffer ) ,[Salt ] =[Base] (in base buffer) pH of a buffer solution lies in the range given below : pH= pK_a +1 In other words any buffer solutions can be used as buffer up two pH units only. depending upon the value of pK_a or pK_b . A buffer is said to be efficient when pH = pK_a or pOH =pK_b , Buffer capacity is maximum when:
