(N/A) $1$. The strongest reducing agent in aqueous solution is $Li$ (Lithium) due to its high hydration energy and low sublimation energy.
$2$. The strongest oxidizing agent among gases is $F_2$ (Fluorine) gas.
$3$. The standard reduction potential of any electrode is measured with reference to the Standard Hydrogen Electrode $(SHE)$,which is assigned a potential of $0.00 \ V$.
