I've got a new toy.
It is a Milton Roy spectronic 20D spectrophotometer.
I bought it for experimentation purposes, and to try and find the concentration of dissolved copper in my silver cells.
It came with a generic manual, but I am clueless on how to use it - youtube has been helpful.
I need to make standard solutions to set up a graph of KNOWN concentrations of copper.
I will then use this graph as a refernece to determine UNKNOWN concentrations of copper from samples of electrolyte drawn from my silver cell.
I am thinking that the standard solutions will need to be prepared using virgin crystal-clear silver nitrate electrolyte - 100 grams of pure silver dissolved in 1 liter of liquid. Then adding a solution of a known quantity of dissolved copper to the electrolyte - but in what proportions?
Or, can I just use dissolved copper in solution and not bother with the copper being in the electrolyte.
I am stumped on how to make these standard solutions, has anyone else ever tried this experiment?
Thanks - kadriver
