12.73 mL cyanide solution was treated with 25.00 mL of 0.015M Ni2+ solution (containing excess Ni2+) to convert the cyanide into complex: 4CN- + Ni2+ Ni(CN)42- the Excess Ni2+ was then titrated with 10.15 mL of 0.0140 M EDTA. The complex Ni(CN)42- is very stable. It does not react with EDTA. Calculate the molarity of CN in original 12.73 mL sample.
