Question

Identify the reducing agent in the reaction Ca +2H → Cat2 + H2 A. Ca B.H C.Cat2 D.H2 ОА OD OB

Answer 1

In redox reaction

the reducing agent loses a electron and oxidizing agent gains a electron

Reducing agent becomes oxidized by losing electron and Oxidizing agent becomes reduced by gaining an electron

Lets see the given reaction

Ca + 2H⁺$\rightarrow$ Ca²⁺ + H₂  

In the above reaction

Ca losses 2 electron and oxidized as Ca²⁺  

And H⁺ gains electron become reduced

So Our answer is Ca or option A
