Question

In the reaction equation shown below, there are three rectants, but in lab you only combined two solutions together. One was 0.001 M aqueous KMnO4 and the other contained aqueous NaNO2 and HCl. Complete the following statements. You may find the flowchart (attached) helpful.

5 NaNO₂ + 2 KMnO₄+ + 6 HCl ---> 5 NaNO₃ + 2 KCl + 2 MnCl₂ + 3 H₂O

The provided aqueous KMnO4 was ___? Explain your reasoning for the classification

a. pure element

b. heterogenous mixture

c. pure compound

d. homogeneous mixture
