Question
A cyanide solution with a volume of 12.98 mL was treated with 23.00 mL of Ni²+ solution (containing excess Ni²+) to convert
the cyanide into tetracyanonickelate (II):
4 CN- + Ni²+ ->>
Ni(CN)
The excess Ni2+ was then titrated with 10.60 mL of 0.01231 M ethylenediaminetetraacetic acid (EDTA):
Ni2+ + EDTA4 → Ni(EDTA)2-
Ni(CN) does not react with EDTA. If 38.70 mL of EDTA were required to react with 30.26 mL of the original Ni²+ solution,
calculate the molarity of CN in the 12.98 mL cyanide sample.
[CN-]=
