Which of the following conditions will make the buffer most efficient?

Which of the following conditions will give the most benefits? Why?

Which one of the following situations makes a firm most efficient ?.

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 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 product a deinite change of pH in a buffer solution, higher will be its buffe capacity. Buffer capcity of solution is maximum under the following conditions [Salt] = [Acid](in acid buffer) [Salt] = [Base] (in base capacity] pH of buffer solution lies inthe range given below pH = pH_(a) +-1 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 = pK_(a) or pOH = pK_(b) Which among the following solution will the most efficient buffer
