Concept introduction:
Sol-gel method:
In this method small molecules are used to prepare solid materials. Sol-gel method converts monomers to sol as colloidal solution which is used as precursor for gel. Mostly used precursors are metal alkoxides. A pictorial representation of sol-gel method is given as follows,
Figure 1
Balanced Chemical equation:
A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.
