Important Topics for NCERT Chemistry Exemplar Solutions Class 11 Chapter 7 – Equilibrium
Chemical equilibrium refers to the state in which both reactants and products are available in concentrations that have no additional learning to change with time so that there is no noticeable change in the properties of the system.
In physical chemistry, Henry’s law refers to a gas law that describes that the amount of dissolved gas in a liquid is relational to its partial pressure above the liquid. The proportionality factor is termed as Henry’s law constant.
Factors affecting Equilibrium
Some of the factors affecting equilibrium are changes in concentration, pressure, and temperature can affect the position of equilibrium of a reversible reaction. Chemical reactions are considered as equilibrium reactions. Equilibrium happens when a definite proportion of a mixture occurs as reactants and the rest exits as products.
Lewis Acids and Bases
A Lewis acid refers to any material, such as the H+ ion, that can receive a pair of nonbonding electrons. Or we can say, a Lewis acid is an electron-pair acceptor. On the other hand, a Lewis base is any material, such as the OH- ion, that can contribute a pair of nonbonding electrons. A Lewis base is thus an electron-pair donor.
A buffer solution illustrates an aqueous solution containing a mixture of a weak acid and its conjugate base, or vice versa. Its pH value differs very little when a small quantity of strong acid or base is added to it.
Common Ion Effect
The common ion effect defines the effect on equilibrium that happens when a common ion is added to a solution. The common ion effect usually reduces the solubility of a solute.
