Determine the effect of the following errors on the measured absorbance for a pink colored 0.50 M solution of Cobalt (II) chloride, CoCl2(aq). a. You rinsed the cuvette with water before adding the sample of CoCl2 (aq).
b. You used a cuvette that had previously contained 0.80 M CoCl2 (aq).
c. The solution was incorrectly made and the concentration was 0.05 M.
d. The spectrophotometer was calibrated with 0.05 M CoCl2 (aq) solution instead of water.
e. You used a cuvette that was scratched on the sides.

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.
