Answer:
is the most electropositive metal.
Explanation:
Sodium is a good reducing agent which means it can lose electrons easily, becoming electropositive. In other words, it can get oxidized. It can displace elements that are lower to it in the reactivity series like hydrogen.
Sodium can displace hydrogen from sulfate ions. The hydrogen gets reduced and sodium gets oxidized.
