A cyanide solution with a volume of 13.38 mL was treated with 28.00 mL of Ni²+ solution (containing excess Ni²+) to convert the cyanide into tetracyanonickelate(II): 4 CN + Ni²+ Ni(CN)2- The excess Ni²+ was then titrated with 10.98 mL of 0.01220 M ethylenediaminetetraacetic acid (EDTA): Ni²++ EDTA+ Ni(EDTA)²- Ni(CN)2- does not react with EDTA. If 38.84 mL of EDTA were required to react with 29.54 mL of the original Ni²+ solution, calculate the molarity of CN in the 13.38 mL cyanide sample. [CN¯] = 0.04 Incorrect M
