Answer:
0.16 M hydrocyanic acid + 0.15 M sodium cyanide
Explanation:
For a buffer system to be regarded as good, it must contain conjugate acid base pair in the solution. A buffer can be made by mixing a weak acid with its conjugate base.
In a good buffer system, their must be a close concentration of the acid base conjugates so as to ensure that the buffering capacity has the same neutralization capacity for any strong acid base system.
