Question

A cyanide solution with a volume of 13 84 mL was treated with 23 00 mL of Ni solution containing excess Ni to convert the cyanide into tetracyanonickelate II 4 CN Ni Ni CN 2 The excess Ni2 was then titrated with 11 09 mL of 0 01331 M ethylenediaminetetraacetic acid EDTA Ni EDTA4 Ni EDTA Ni CN does not react with EDTA If 38 21 mL of EDTA were required to react with 29 14 mL of the original Ni solution calculate the molarity of CN in the 13 84 mL cyanide sample
