Question 3

What is the ion electron equation for NO2- —-> NO3-

Answer 3

NO2- + H2O —> NO3- + 2H+ + 2e-

Question 4

What are some examples of oxidising and reducing agents?

Answer 4

Oxidising agents - H2O2 - Bleach
Can destroy viruses and kill bacteria

Reducing Agents - CO gas - Used to extract metal from their compounds.

MnO4- and Cr2O72- are strong reducing agents in acidic solutions.
