Some Basic Concepts of Chemistry

Jeremias Richter, a German chemist, coined the term Stoichiometry that refers to the quantitative analysis of the  involved reactants and products of a chemical reaction. This word is derived from Greek words, “Stoikhein”, meaning element and “metron” meaning measure.  What Is Stoichiometry? We can define Stoichiometry in simple words as the calculation of reactants as […]

If you ask what is Colloidal solutions and suspensions are, they are a mix of substances suspended in a regular pattern in a fluid. A colloid or colloidal system is a dispersion of one substance (the dispersed phase) in another (the dispersion medium), where the dispersed-phase has the same order as the medium but on

pH Scale Introduction: A pH scale is well recognised as a useful tool for comparing various chemicals. Due to the continuous rather than discrete nature of the scale, it is feasible to employ both whole numbers and accurate decimal values. Orange juice, for instance, is entirely drinkable at a pH of 3.3 to 4.2.  

We all know that whole numbers can be extended indefinitely, but we can’t write such large numbers down on a piece of paper because they’re too big. Additionally, the numbers that appear at the millions place after the decimal point need to be expressed in a more straightforward manner. As a result, it is difficult

The word “molecule” derives from the Latin word “molecula,” which refers to a mass unit. Its original definition, “the smallest unit of a substance that yet preserves the qualities of that substance,” was intended to be encompassed by this designation. “An atom is a body that cannot be cut in two; a molecule is the

Mole Concept and Molar Masses When determining molar mass, the first step is to write out all the elements in the molecular formula. Depending on the number of atoms in the unit cell, square brackets are used to enclose groups of atoms. The atomic masses or atomic weights of each element are then listed next

Introduction Mole Concept And its Working Principle The idea of mole is  a convenient way of expressing a substance’s quantity. We have two parts in measurement: the numerical magnitude and the units in which the numerical magnitude is expressed. The magnitude is ‘2’ and the unit is ‘kilogramme’ when the mass of a ball is

We’d all like to know how many molecules are present in a particular substance we’re interested in. Molecules and atoms are extremely small objects, both in terms of size and mass. The molar mass is defined as the weight of one mole of a sample. Calculate the molar mass of a molecule by connecting the

What is the Melting Point of a Substance? The temperature at which water transforms from solid ice to liquid water is known as the melting point. At this temperature, water’s solid and liquid phases are in balance.  Because the melting point of water varies significantly depending on pressure, one cannot designate a particular temperature as

What is the Definition of the Melting Point? Generally, the melting point of a substance is defined as the point at which it transforms from a solid to a liquid. The temperature at which a solid transforms into a liquid at atmospheric pressure is referred to as the liquid’s melting point. This is the point
