Flamephotometric determination of sodium is based on the measurement of the absorbance, A, on three standard solutions with known concentration of sodium ions: Data: ([Na+]; A): (0.
Plot the standard curve using the figure to the right: A solution is prepared from 34.
0 mg of sodium bromide (M=102.
9g/mol) dissolved in water (V=100 ml).
This solution is out of the measuring range and needs to be diluted.
Suggest how many times this solution should be diluted to give a concentration within the measuring range.
Predict the absorbance (A) of the this diluted solution.
