Use equation: (C=m/V). Now, the known concentration of copper(ll) ion solution and a colorimeter to produce a cu(ll) ion conc./absorbance calibration curve. you will be able to read its conc. from the curve.
A titration is a technique in which a solution of known concentration is used to determine the concentration of an unknown solution. The titrant (the known solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.
A calibration curve is a way to identify the concentration of an unknown compound. These curves use data points of known compounds at varying concentrations, and researchers or developers can use these curves to find where an unknown substance plots.
