Concept explainers
a)
Interpretation:
The oxidation half reactions have to be balanced and the stoichiometry coefficients have to be given.
Concept Introduction:
Half reactions:
A half reaction can be defined as component of redox reaction that is either
b)
Interpretation:
The number of molecules of Oxygen that is necessary to balance the half reaction by reduction of Oxygen has to be calculated.
c)
Interpretation:
The number of moles of Oxygen that would be necessary for oxidation has to be calculated.
d)
Interpretation:
The chemical oxygen demand of the sample has to be calculated.
e)
Interpretation:
The concentration in
Concept Introduction:
The number of moles per litre of the solution is called as Molarity. Molarity can be defined as the moles of solute (in grams) to the volume of the solution (in litres). The molarity of a solution can be given by the formula,
