The Electromotive Force or the EMF, measured in coulumbs of charge. This pressure is developed or the electrical intensity or from electrical source or energy. It’s a device that converts any energy form into electrical energy that is later measured with coulumbs of charge. EMF which is Electromotive Force is denoted by, ℰ. So, emf … Read more
The lead accumulator refers to a secondary cell as the electrical energy doesn’t generate itself inside the cell, but it is stored prior to an external source. It’s a reversible cell as the cell reactions are in the reversed state if external emf is suitably bigger than this cell’s emf which is applied. Therefore, … Read more
Electrolytic Cells Voltaic cells are operated by the spontaneous chemical reaction, which produces the electrical current through the external circuit. These cells are significant as they are the base for batteries which boost modern society. However, they don’t exist as the only type of electrochemical cell. In each case, the reverse reaction is non-spontaneous plus … Read more
Electrolysis Process In simple words, the electrolysis process is the decomposition of the given element under the impact of the electric current. Or, Electrolysis refers to a method which uses a DC (direct current or direct electric current) to operate in other respects, the chemical non-spontaneous reactions. As per the financial perspective, electrolysis plays an … Read more
According to Kohlrausch’s law, the equivalent conductivity of electrolyte on the infinite dilution is equal to total of conductance of both cations and anions. Equivalent limiting molar conductivity of the electrolyte refers to the algebraic sum of equivalent limiting molar conductivities of its constituent ions. Mathematically, Where, λo+ = cations’ limiting equivalent conductivities … Read more
Both conductivity and molar conductivity depends upon the electrolyte’s concentration. The Molar Conductivity and Conductivity of both strong and weak electrolytes decreases as there’s decrement in concentration as the ions’ number per unit volume which carries the current in the solution goes down on dilution. Solution’s Conductivity at a specific concentration = Solution’s Conductance kept … Read more
The usage of solutions’ colligative properties in the molecular masses determination of different compounds is one of the easiest and simplest ways. Since solutions’ colligative properties are dependent on the solute’s number of molecules only in them, this method is particularly in use to determine complicated molecules’ molar masses, and the molar masses of polymers, … Read more
Specific and molar conductivity Here is the description of molar conductivity and specific conductivity. Material’s conductance is material’s property because of which a material lets the ion’s flow going through itself and therefore, conducts electricity. Generally, it’s described as resistance’s reciprocal of that particular material. S (Siemens) is the SI unit of conductance. … Read more
The specific conductance or the conductivity of the electrolyte solution is defined as the measurement of its capacity to conduct the electricity. Conductivity’s SI unit is (S/m) i.e. siemens per metre. The measurements of conductivity are regularly used in many environmental and the industrial applications as a reliable, inexpensive, and fast way to measure an … Read more
What is the Van’t Hoff Factor? The Van’t Hoff factor ‘i’ gives you the introduction on effects of the solutes on solutions’ colligative properties. It is represented by the symbol ‘i’. The Van’t Hoff factor can be outlined as ratio of formation of particles’ concentration when the substances dissolves to substance’s concentration by mass/weight. The … Read more
