Please show calculations for all 4 trials
3cer's law states that the absorbance of a solution is directly proportional to the molar Concentration of a solution. If you plot absorbance versus molar concentration (molarity), the esulting graph yields a straight line. The equation for the straight line can be used to determine he concentration of an unknown solution from a measurement of its absorbance. You need to prepare 10.0 mL of diluted Cuso, solutions with the concentrations listed for Trials...
If the original sodium tartrate solution had a concentration of
1.00 M instead of 0.100 M, what would the concentration of copper
be in a solution created by combining 10 mL of it with 10 mL of the
0.100M copper (II)sulfate solution. Use the Ksp you found in the
experiment.
For the ionic solid copper tartrate, the solubility equilibrium
reaction is: CuC4H4O6 (s) Cu2+ (aq) + C4H4O6 2- (aq) Just like any
equilibrium reaction, an equilibrium expression can be created....
