Expression of Concentration of Solutions-Methods, Solids in Liquid Solution & Solubility of Gases in Liquids

December 24, 2024 by Neeraj Anand, Param Anand
Solution being diluted or concentrated; this is a qualitative way of expressing the concentration of the solution. A dilute solution means the quantity of solute is relatively very small, and a concentrated solution implies that the solution has a large amount of solute. But these are relative terms and do not give us the quantitative concentration of the solution.

Fuel Cell-Definition, Working, Types, Applications

December 24, 2024 by Neeraj Anand, Param Anand
Fuel cell can be defined as an electrochemical cell that generates electrical energy from fuel via an electrochemical reaction. Fuel cells require a continuous input of fuel and an oxidizing agent (generally oxygen) in order to sustain the reactions that generate the electricity. Therefore, these cells can constantly generate electricity until the supply of fuel and oxygen is cut off.

Corrosion-Definition, Corrosion Types, Rusting, Effects, Prevention

December 24, 2024 by Neeraj Anand, Param Anand
Corrosion is one of the most common phenomena that we observe in our daily lives.   you must have noticed that some objects made of iron are covered with an orange or reddish-brown coloured layer at some point in time. The formation of this layer is the result of a chemical process known as rusting, which is a form of corrosion.

Solutions MCQ’s With Explanation For Class 12 CBSE Chemistry Worksheet

December 24, 2024 by Neeraj Anand, Param Anand
A homogeneous mixture of two or more components is called a solution. The properties and composition of the mixture are uniform throughout the solution. A solution is made up of a solvent and a solute. The solvent is present in the largest quantity and the solute is present in lesser quantity. The solute is dissolved in the solvent. The solute and the solvent together form a solution.

Arrhenius Equation-Effect of Temperature on Rate of Reaction, FAQ’s

December 24, 2024 by Neeraj Anand, Param Anand
Temperature is one of the parameters that can affect the rate of a chemical reaction considerably. We have often seen milk boiling on a gas stove. The rate at which a specific quantity of milk boils depends on the flame of the stove. If the flame height is maximum, the milk boils in less time and if the flame height is minimum, the milk takes more time to boil. Here the flame height resembles temperature.

Integrated Rate Law Equation for Zero Order and First Order Reaction

December 24, 2024 by Neeraj Anand, Param Anand
An equation representing the dependence of the rate of reaction on the concentration of reacting species is known as a differential rate equation. The instantaneous rate of reaction is expressed as the slope of the tangent at any instant of time in the concentration-time graph. Hence, it is very difficult to determine the rate of reaction from the concentration-time graph. Therefore, we integrate the differential rate equation to obtain a relation between the concentration at different points and rate constant. This equation is known as the integrated rate equation. For reactions of different order, we observe different integrated rate equations.
