As a rule of thumb, if elemental hydrogen is in a reaction and it's NOT reacting with a metal, it's the reducing agent.
Carbon dioxide is the reducing agent.
Fluorine is the strongest reducing agent.
fructose is non-reducing sugar
I believe you're talking about redox electroplating in a salt medium. If that's the case, then nickel is in fact the reducing agent. Reducing agent loses electrons, oxidizing agent gains.
No, lithium is a strong reducing agent.
Carbon dioxide is the reducing agent.
depends on what else is in the equation
This reducing agent.
it is a reducing agent
NO2(g)+SO2(g)-->NO(g)+SO3(g) here NO2 act as a oxidising agent
Reducing
it is both oxidizing as well as reducing agent
Hypo is a reducing agent when combined with Na.
A substance that is good at reducing another atom
If you had the equation of H2O2(aq) ==> H2O(l) + O2(g), it wouldn't be balanced, so is incorrect. If it were 2H2O2 ==> 2H2O + O2, then it would be balanced, and H2O2 would be an example of a disproportionation reaction, where H2O2 is both the oxidizing and reducing agent, i.e., the O is both oxidized and reduced to form H2O and O2. Not sure if this is what you are looking for as the question is rather vague.
sodium hydroxide is a reducing agent and is a strongly alkaline caustic used in manufacturing soap.
