Save Question 4 (Mandatory) (2 points) Given the following reaction of Fe3+ (aq) SCN- (aq) Fe(SCN)2+, calculate the concentration (in Molarity) of SCN- knowing the standard volume of SCN- in mL is 1.0. Refer to the theory and procedure sections and report your answer without units in decimal notation (ie not scientific notation) Your Answer: Answer Save Question 5 (Mandatory) (2 points) Given the following reaction of Fe3+ (aq) SCN (aq) Fe(SCN)2+, calculate the concentration (in Molarity) of Fe(SCN) knowing the standard volume of SCN in mL is 2.0. Refer to the theory and procedure sections and report your answer without units in decimal notation (ie not scientific notation) Your Answer:

Explanation / Answer

4. the concentration of SCN-

1.0 ml of 0.00150 M SCN- is taken

Final volume of solution = 10 ml

concentration of SCN- in the final solution = 0.00150 M x 1 ml/10 ml = 0.00015

5. the concentration of SCN-

2.0 ml of 0.00150 M SCN- is taken

Final volume of solution = 10.0 ml

concentration of SCN- in the final solution = 0.00150 M x 2 ml/10 ml = 0.0003
