Question
Calcium reacts with nitric acid according to the reaction:
Ca(s)+2HNO3(aq)Ca(NO3)2(aq)+H2(g)
Identify the oxidizing agent
Identify the oxidizing agent.
Identify the oxidizing agent.
D.) Ca(s)
I thought that the answer was H2 but it said that H2 is not the correct answer. I know that the oxidizing agent is the one that is reduced, I choose D because H goes from a +1 charge to a 0 charge in H2 gas.
A.) Ca(NO3)2 B.) HNO3(aq) C.) H2(g)D.) Ca(s)
I thought that the answer was H2 but it said that H2 is not the correct answer. I know that the oxidizing agent is the one that is reduced, I choose D because H goes from a +1 charge to a 0 charge in H2 gas.
Explanation / Answer
The correct answer is B, the one that is being reduced is the H+ ion, which will act as the oxidizing agent of calcium.
