Question

Classify each of the following statements about the lab as True or False.

The Beer's Law constant needed for the lab will be measured as part of the experimental procedure.

[Fe3+]o refers to the final equilibrium concentration of Fe3+ ion in the reaction mixture.

The equilibrium reaction studied in this lab is: FeSCN2+ ⇐⇒ Fe3+ + SCN- (⇐⇒ is being used in place of the equilibrium symbol)

The reaction will be monitored using spectrophotometry to measure the absorbance of the SCN- in the mixture.

Answer 1

1. The Beer's Law constant needed for the lab will be measured as part of the experimental procedure. - True statement.

2. [Fe³⁺]^o refers to the final equilibrium concentration of Fe³⁺ ion in the reaction mixture. - False statement

3. The equilibrium reaction studied in this lab is: FeSCN²⁺ ⇐⇒ Fe³⁺ + SCN^- (⇐⇒ is being used in place of the equilibrium symbol) - True statement

4. The reaction will be monitored using spectrophotometry to measure the absorbance of the SCN^- in the mixture. - True statement
