Hbr + h₂so₄ so₂ + br₂ + h₂o whats the oxidizing agent and whats the reducing agent?

Sulfur is the oxidizing agent and bromine is the reducing agent.

Explanation:

Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases.

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.

Reduction reaction is defined as the reaction in which an atom gains electrons. Here, the oxidation state of the atom decreases.

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.

For the given chemical reaction:

The half reactions for the above reaction are:

Oxidation half reaction:  

Reduction half reaction:  

From the above reactions, bromine is loosing its electrons. Thus, it is getting oxidized and is considered as a reducing agent.

Sulfur is gaining electrons and thus is getting reduced and is considered as an oxidizing agent.

Hence, sulfur is the oxidizing agent and bromine is the reducing agent.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
