Describe Hess’s Law

Hess’s law is known as after Russian Chemist Germain Hess. Hess helped formulate the early standards of thermochemistry. His famous paper, which was published in 1840, included his law. Hess’s law: If the initial and…

What is Ionic Product of Water?

Ionic product of water: The dissociation of water, H2 O+ ↔ H+ + OH– According to law of mass action, K = [H+] x [OH–]…
Why conjugated base of strong acid is weak and conjugated base of weak acid is strong?
Chemistry

Why conjugated base of strong acid is weak and conjugated base of weak acid is strong?

The conjugated base of strong acid is weak and the conjugated base of weak acid is strong. It can be explain—clearly by reversible reaction. HB…

Chemistry

Explain Apply of Le Chateliar Principle

The principle of Le Chateliar: When a system is at equilibrium, a change in any one of the factors (such as temperature, pressure, concentration) upon…
Why the Value of Equilibrium Constant KC cannot be Zero or Infinity?
Chemistry

Why the Value of Equilibrium Constant KC cannot be Zero or Infinity?

The constant KC is called the equilibrium constant and applies to reactions in solution. It contains only concentration terms. It should not included terms for…
What is Chemical Equilibrium?
Chemistry

What is Chemical Equilibrium?

Chemical equilibrium: A chemical equilibrium in a system is the state of the system when there is no observable change in the concentration of the…
What is Dynamic Equilibrium?
Chemistry

What is Dynamic Equilibrium?

Dynamic equilibrium: When a reversible reaction reaches at equilibrium, then it seems to be stopped. Because, in this situation there seems to no change in…
