Enthalpy is the measurement of energy in a thermodynamic system. The quantity of enthalpy equals the total content of heat of a system
Buffers are generally characterised by pH range by which they maintain a more or less constant pH by their buffer capacity.
According to Hund’s rule: Before the double occupation of any orbital, every orbital in the sub level is singly occupied.
Pauli exclusion principle states that no two electrons present in a single atom will have an identical set or will have the same quantum numbers
Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other
water that contains a required quantity of dissolved minerals (like calcium and magnesium) ,Water hardness is usually measured as calcium hardness in milligrams per litre (mg/l)
The Aufbau principle highlights the way in which the electrons are filled in the atomic orbitals of an atom in its ground state
Hybridization is process, where the atomic orbitals having different shape and energy inter mingle together to form a set of similar orbitals
free energy refers to the amount of internal energy in a thermodynamic system that is available to do work. There are different forms of thermodynamic free energy
Electron affinity is the amount of energy required to detach one electron from a negatively charged ion of an atom or molecule
Sedimentation is the simplest separation method and an essential concept.in the separation process the solids are separated from the liquids
The Molecular orbital theory was utilised initially to emphasize the bonding in molecules as the valence band theory could not explain the bonding in molecules.
At equilibrium Nernst equation is given by, E0 = (2.303RT/nF) log10Keq Where, Keq = equilibrium constant and F= faradays constant, and gives a relation between standard electrode potential.
Biological Oxygen Demand (BOD) estimates the amount of biodegradable organic matter that is present in polluted waters, effluents and polluted waters
It is a theoretical model which details the molecular composition of the gas in terms of a huge number of sub microscopic particles that contain both atoms and molecules.
Elastomers are polymers showing properties of both viscosity and elasticity and are also called viscoelasticity. The molecules of elastomers held together by weak intermolecular forces
Coagulation is a chemical process that is used in water treatment,a coagulant is added to remove the dispersed oils.
