I need help with this question, please.
What A chemistry graduate student is given 100. mL of a 1.10 M hydrocyanic acid (HCN) solution. Hydrocyanic acid is a weak acid with Ka = - 10 =4.9 x 101 mass of KCN should the student dissolve in the HCN solution to turn it into a buffer with pH = 8.95? You may assume that the volume of the solution doesn't change when the KCN is dissolved in it. Be sure your...
