Analysis of nickel (II) in solution by EDTA titration

I am a chemistry student in London(12th year) and I am stuck on why we need to do titrations!After standardisation of a solution of EDTA, you can determine Ni solution but what are the possible applications for this type of Ni analysis?

We need titrations for exactly the same reasons that we need scales and measuring sticks, Miss B. Why would you need to know how many ounces of jelly beans are in a bag, or the circumference of your ring finger or hat band? Obviously there are a number of possible answers to each question. You might titrate drinking water for nickel to be sure it's safe to drink; you might titrate a solution of nickel to get the right proportions if you were trying to formulate a nickel compound; you might titrate it to see if it's at a good concentration for optimized nickel plating. I hope your teacher asked for at least four possible reasons rather than three :-)

I am a chemical lab technician. I do this very titration all the time at work. the titration is a 5Ml. sample of nickel plating bath, 10 mls. of ammonium hydroxide and 1 gram of murexide [affil links]. The reason we do this titration is to determine the percent of nickel metal in the bath. The bath will plate best at exactly 100%..but often times the results will be 105% or more...this shows that the controller for the bath needs to be adjusted, thus, the reason for the titration would be to control the nickel metal in the bath for optimum plating performance.
