Li by Flame Emmision: Report Template
Using Excel, prepare an analytical curve by plotting Li reading vs. mg Li/L (abscissa). Include y error bars of ± one standard deviation. Is the graph linear? Turn in the graph.
Report the equation for the best-fit line. If the graph is nonlinear, only use the linear portion of the curve to calculate the best-fit line.
Report the concentration of Li, in mg/L, in the “unknown” solution obtained by diluting to the mark in the 100 mL flask. Remember to take into account the dilution that occurred before measurement.
