What is about solution?
A solution is a homogeneous mixture of two or more than two substances. Read More →
In azeotropic mixture showing positive deviation from Raoult’s law what is the volume of mixture?
The azeotropic mixture which show positive deviation from Raoult’s law decrease the forces of attraction among themselves, hence the volume of the mixture increases than the expected volume. Read More →
In fuel cells chemical energy is converted to the which type of energy?
In fuel cells one of the substance is oxidized which is called a fuel cell. It loses electrons so chemical energy is converted into electrical energy. Read More →
How can be the electrode reaction of a voltaic cell reversed?
The electrode reaction of a voltaic cell can be reversed, when the external circuit is employed to supply the source of electricity. Read More →
For what calculation the study of colligative properties is useful?
Colligative properties are used to calculate the molar masses of solutes. Anyhow the solute should be non-volatile and non-electrolyte. Read More →
What have the very dilute solution of glucose in water?
When solution of glucose in water is very dilute, then the molecules of glucose are free in the solution. In the case of concentrated solution, 2-3 molecules or even more are joined with each other to form bigger particles which are depressed in water. Read More →
What value of electrode potential of standard hydrogen electrode is arbitrarily taken?
The electrode potential of SHE is arbitrarily chosen as zero. Read More →
What is the work of salt bridge?
The purpose of salt bridge is to carry the ions from one half cell to the other. It maintains the electrical neutrality in two half cells. Read More →
What is about the electromotive force of the cell?
The electromotive force of the cell, may be sum or difference of two electrodes potentials. If both electrodes are above SHE or both are below SHE then electrodes potentials are subtracted to get the e.m.f. If one of electrodes is above SHE and other is below SHE, then the electrodes potential are added... readmore
What is called the process when a non-spontaneous redox reaction is carried out by using electrical current?
When a non-spontaneous redox reaction is carried out by using electrical current, then the process is called electrolysis. Read More →
