Cаlculаte the percent dissоciаtiоn fоr a 0.010 0 M HCN solution. Ka = 6.2 × 10−10 for HCN. (Report at least 3 decimal places) Hint: Solve the weak-acid equilibrium for [CN−], ignoring the change in the formal concentration of HCN. Divide the concentration of the cyanide ion by the formal concentration and multiply by 100.
