2.5 % Light Transmittance Associated with Various Concentrations of Dye Dye Solution % Concentration of Dye % Light Transmittance 1 0 (DH2O only) 100 2 10 3 25 4 75 5 100 (stock) Unknown A, B, C, D (circle yours) What relationship exists between concentration of dye and % transmittance? Part C2: The Standard Curve Procedure Plot the 0%, 10%, 25%, 75%, and 100% data from Table 2.5 on Fig. 2.2 Attempt to draw a fit” line through the scatter of data points. Do not simply connect the “best dots. Make your line pass through the spread of the dots. This line represents a “average” standard curve and illustrates the relationship between percent concentration of a dye solution and percentage of light transmitted. Use this standard curve to complete Part C3
