Titration is a process to determine the molarity of a base or an acid. In this process, a reaction is carried out between the known volumes of a solution with a known concentration, against the known volume of a solution with an unknown concentration. A buffer is an aqueous solution which has highly stable pH.
It is a blend of a weak acid and its conjugate base or vice versa. On adding a small amount of base or acid to buffer, its pH hardly changes. In buffer when hydrogen ion is added, it will be neutralized by the base in the buffer. Hydroxide ion will be neutralized by the acid. On the overall pH of the buffer solution, these neutralization reactions will not show much effect. While when you select an acid as a buffer solution, try to use an acid that has a pH closed to your desired pH.
Mole is the unit used to define the number of chemical substance present in a substance. It is the amount of substance which consists of the same number of chemical units as there are atoms in exactly 12 gram of pure carbon How will you calculate how many moles of glucose present in mL of 5.
Both methods are used to separate the components present in the solution based on the melting points. Both techniques are used to the amount of chemical present in the solution. However, they are almost similar but differs in. Valency is a property of groups or atoms, equal to the number of atoms of hydrogen that the group or atom could combine with or displace it in forming compounds.
In a molecule when a hydrogen atom is less than the ratio of a carbon atom, then such molecules are referred to as an organic molecule.

Levorotation and Dextrorotation are referred to the properties of plane polarized light when light rotates clockwise when it approaches the observer is then known as dextro-rotation and when the light rotates anti-clockwise then it is referred to as levorotation. A compound which exhibits a dextro-rotation is referred to as dextro-rotatory and which exhibits levorotation is referred to as levorotatory.
