In order to analyze the wastewater containing cu2+ from a manufacturing process, 1.0L of water was evaporated to 10.0mL, then placed in a spectrophotometer tube. The absorbance was found to be 0.30. Using your calibration curve, calculate the number of milligram of Cu2+ in 1.0L of wastewater.
Is there a reference website that lists all chemicals and the less costly yet effective analysis method for determining concentrations of their ions
