Worked Solution & Example Answer:The following two unbalanced equations represent processes which are part of the nitrogen cycle - VCE - SSCE Chemistry - Question 10 - 2007 - Paper 1
Step 1
In process I, NH₃(aq) is
Answer
In process I, the species NH₃, or ammonia, is acting as a base. It gains a proton, converting to NH₄⁺, which is the ammonium ion. Thus, NH₃ is classified as a base in this context.
In process II, NH₄⁺(aq) is undergoing oxidation as it transforms into NO₃⁻(aq), the nitrate ion. During this process, NH₄⁺ loses electrons, indicating that it is being oxidised.
