Titration - is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte. Purpose - Titration is the detection of the equivalence point,the point at which chemically equivalent amounts of the reactants have been mixed. The amount of reactants that have been mixed at the equivalence point depends on the stoichiometry of the reaction. Titration uses in Real Life - Food Industry. Cosmetic Industry. Wine Industry. Pharmaceutical Industry Biodiesel Manufacturing. Waste water Management. Medical Diagnosis. Acid Rain Analysis.

VARIATIONS WITHIN A CRYSTAL SYSTEM : A. Primitive Unit Cells/Simple Unit Cells(PC/SC) : When constituent particles are present only on the corner positions of a Unit cell, it is called a simple. Example : Cubic, Tetragonal, Orthorhombic, Monoclinic, Triclinic, Hexagonal, Rhombohedral or Trigonal. Calculation : • Effective number of atoms per unit cell • Contribution of an atom in the unit cell = (1/8)th of atom. So, Formula : { Effective no. of atoms = Corners of cubic×contribution of an atoms in one unit cell} 8×1/8 = 1 answer. B. Body-Centred Cubic(BCC) : Such a unit Cells contains one constituent particles (atom, molecule, ion) at its body centre besides the ones that are it's corners. Example : Cubic, Tetragonal, Orthorhombic. Calculation ...
