In chemistry, an equivalence point is a term that is used while performing titration. It applies to any acid-base or neutralization reaction technically. Definition: The equivalence point of a chemical reaction is the point at which equal quantities of reactants are mixed chemically. In other words, while titrating, it is a point where the amount … Read more
The order of the reaction is a relationship between the rate of a chemical reaction and the concentration of the species. Definition: The order of reaction is defined as the power dependence of the rate on the concentration of each reactant. Once the rate law of a reaction is determined the same law can be … Read more
Introduction It is also known as the Haber – Bosch process or Synthetic Ammonia process. Haber’s process is considered as one the most beneficial and efficient industrial processes to be used for the production of ammonia which is a colorless gas having a distinct odor. In the 20th century Fritz Haber, a German chemist developed … Read more
Strong Bases Definition According to Arrhenius, bases are compounds that releases hydroxide ions OH– in aqueous solution. Strong bases are those bases which can dissociates completely to give hydroxide ions in aqueous solution. Such as, KOH(aq) → K+(aq) + OH–(aq) That means, one mole of strong base dissociates in aqueous solution to give one mole of hydroxide … Read more
Statement of Hess’s Law Hess’s law of constant heat summation states that the total enthalpy change in a particular reaction is constant regardless whether it occurs in one step or more. Explanation of Hess’s Law According to Hess’s law, if A reacts to form the product B, it doesn’t matter how many steps involved to … Read more
Lattice Energy Definition Ionic compounds are more stable because of their elctrostatic force between the two opposite ions. After the formation of ions, they combine together to form ionic compound. The energy released in this process is known as lattice energy or lattice enthalpy. That means, energy released when a cation and a anion combine … Read more
Introduction to the water ionization constant Kw Pure water undergoes auto-ionization or self-ionization by donating or accepting a proton between two molecules of water to form H3O+ and OH– ions. This is also known as autoprotolysis or amphoteric nature of water. The hydronium ion is a very strong acid and hydroxide ion is a very … Read more
Introduction of collision theory According to this theory, a chemical reaction only takes place when two reacting molecules collide with sufficient kinetic energy. The reacting molecules collide with each other to perform a reaction. But not all the collisions are effective. When the reacting molecules collides with proper orientation and with sufficient kinetic energy, then … Read more
