Balance the following skeleton reactions and identify the oxidizing and reducing agents:(b) CrO₄²⁻(aq) + Cu(s) → CrOH₃(s) + CuOH
andrew-mc [135]

The balanced skeleton reactions are given below

2CrO₄²⁻(aq) + 3Cu(s)  +8H_{2} O(l) → 2Cr(OH)₃(s) + 3Cu(OH)₂(s) + 6OH^{-}(aq)

The oxidising agent and  reducing agents are Cr and  Cu .

There are following steps involve in balance redox reaction in basic medium .

  • First divide the reaction into two half reactions which give oxidation and reduction half reaction.
  • Then balance the elements other than oxygen and hydrogen atom.
  • Balance the oxygen atom by adding H_{2} O where number of oxygen is less .
  • Balance the hydrogen atom by adding H^{+} on another side of where water molecule added.
  • Add OH^{-} ions to both sides to neutralize  H^{+} ion.
  • Combine  H^{+} and OH^{-} ion to make H_{2} O .
  • Balance the charge by adding e^{-} .
  • Add the half reaction  .

The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction  is called reducing agent .

How does bohrs model agree with Thomson model
Airida [17]
Bohr's Model agree with Thompson's model because Bohr concluded that packets of energy are absorbed or emitted by the atoms when an electron changes shell. Thompson's conclusion states that atoms have small, negatively charged particles (referring to Electrons) as part of their internal structure.
