Asked by Ash

A dilute solution of which acid is most likely to produce a reduction product other than H2 when it reacts with a metal?
A)HF
B)HCL
C)HNO3
D)H2SO4

Answer is C. I know it has something to do with it producing oxygen, but I really don't understand where that comes from. Please explain!

The most common reduction products when using HNO3 (besides H2 gas) is NO and/or NO2. VERY strong reducing agents can even produce NH3 from HNO3. but that is not nearly as common as the NO/NO2 production.
