Question

In this experiment the stoichometry of nickel ammine complex is confirmed by spectroscopy. The technique used is Job's method of continuous variation and the procedure is similar to the one used earlier this semester for the iron-thiocyanate complex. The mole ratio of ammonia to nickel when the absorbance of the solution is at a maximum is determined by plotting the two best straight lines through the data points. Suppose that the mole fraction of ammonia in the solution at the point of maximum absorbance is equal to .33. What is the stoichiometry of the complex formed between Ni2+ and ammonia

Enter the ratio in whole numbers seperated by a colon.
Stoichiometry of the complex formed between Ni2+ and ammonia??????

Explanation / Answer

mole fraction of ammonia at maximum absorbance = 0.33

So ratio = 0.33 : 1-0.33

= 1:2

So formula =Ni[NH3]2+
