Which of the following solutions containing weak acid and salt of its conjugate base has maximum buffer capaity?

A solution capable of maintaining its pH relatively constatn, when either excess acid or excess base is added, is said to be buffered While it is not usually considered a buffered solution, a concentrated solution (10^(-2) M and higher) of a strong acid or stong base is buffered against large changes in pH when acids or bases are added. Buffered solutions are usually those containing a wealk acid and a salt of that weak acid or a weak base and the salt of that weak base. For example a solution containing HAc and NaAC resists large change in pH when acid or alkali is added. For a buffer solution Buiffer capacity is defined as the number of moles of a strong acid or a strong base that causes 1 of the buffer to undergo a 1 unit change in pH. Buffer capacity is maximum when the molar ratio of the two components is unity and the buffer solution is considerred good. Which solution is not a buffer solution ?

Which species has the lowest concentration in a solution prepared by mixing 0.1 mole each of HCN and NaCN in 1 L solution? K_(a)(HCN)=10^(-10)

A basic buffer contains equal concentration of base and its salt. The dissociation constant of base is 10^(-6) . Then the pH of the buffer solution is

pH of 0.1 M NaA solution is : Given : (K_b)_(A^-)=10^(-9)

A buffer solution is made by mixing a weak acid HA (K_(a) =10^(-6)) with its salt NaA in equal amounts. What should be amount of acid or salt that should be added to make 90 mL of buffer solution in which if 0.1 mole of strong acid are added into 1 L of this buffer solution then change in pH is unity ?

What is the solubility of Al(OH)_(3) , ( K_(sp)=10^(-33) ) in a buffer solution of pH=4?

Calculate the ratio of sodium formate and cormic acid (K_(a)=2xx10^(-4)) in a buffer solution of pH=4.3.
