Question

Make a plot of the data in Table 2 (Experiment 7, Discussion) on the supplied graph paper on the reverse of this page. Below write the value of lambda_max for Eryrhrosin B as determined from your graph. Also, write this value in the DATA Section A. You pipet 2.00 mL of 2.46 Times 10^-2 M HCl into a 50.00 mL volumetric flask. What is the molarity of the diluted solution? In order to better understand the dilutions you will prepare in part A, "Calibration Curve," complete the following schematic drawing of the procedure that is described in this section. (Assume initial stock solution (I) contains 0.7340 g Eryrhrosin B per liter.)

Explanation / Answer

1) Please provide the data in Table 2 inorder to prepare the plot

2) Use the relation:

Minitial * Vinitial = Mfinal * Vfinal

Here Minitial = 0.0246 M

Vinitial = 2 ml

Vfinal = 50 ml

Therefore, Mfinal = 0.0246 * 2/50 = 0.000984 M i.e 9.84 * 10^-4M

3) Experimental background information is required to complete the chart.
