A 10 mL calibration solution is made by mixing 5 mL of 0.200 M Fe(NO3)3, 1.5 mL of 0.002 M KNCS, 1 mL of 0.1 M nitric acid and 2.5 mL H2O. What is the final concentration of the NCS—ion?

Would you use M1V1 = M2V2 for this problem?

  • Also, 1 mL of this solution is then diluted to a final volume of 25 mL with DI water. What is the new concentration of NCS-? Linh commented over 3 years ago
