  • Reducing agent
  • B
    Dehydrating agent
  • C
    Sulphonating agent
  • D
    Highly viscous

Answer

Correct option: A.
Reducing agent
a
$H _2 SO _4$ is a strong oxidizing agent it can oxidize both metals and non metals. So its not a reducing agent.

$Mg + H _2 SO _4 \rightarrow MgSO _4+ H _2$
