Chemical Formula of Bleaching Powder & its Uses
Calcium hypochlorite is the chemical name of Bleaching Powder, and its chemical formula is Ca(ClO)2. Ca(ClO)2 is called Calcium Oxychloride. Also Read: pKa in Chemistry : Definition Bleaching Powder Preparation The reaction of chlorine gas (produced from the chlor-alkali process) on dry slaked lime (Ca(OH)2). Ca(OH)2 + Cl2 → CaOCl2 + H2O gives Bleaching powder (CaOCl2) From the above reaction, […]

What are Radio Active Elements ? List of Radio Active Elements
The elements that are formed naturally by nuclear fission or through the intentional synthesis in nuclear reactors or particle accelerators are called Radio Active Elements. All elements can have radioactive isotopes. If enough neutrons are added to an atom, it becomes unstable and decays. The increasing atomic number does not necessarily make an atom more unstable. Natural radioisotopes […]

List of Elements of Periodic Table With Names
Elements in the periodic table are arranged according to their atomic number and atomic mass from 1 to 118. There are still some elements to be known yet. Scientists are yet to discover many more elements and adjust the periodic table accordingly. But the list of the periodic table elements known till now, are given below: ElementNo. Element Name Element Symbol […]

What is Normality of a solution ? How to Calculate it ?
The normality of a solution is defined as the equivalent gram weight of any solute per liter of solution. It may also be known as the equivalent concentration. It is denoted by the symbol ‘N’. A gram equivalent weight or equivalent measures the reaction capacity of ion, molecule, etc. The equivalent value is calculated by the molecular weight and […]

Equivalent weight And It’s Calculation
The equivalent weight is defined as the weight (or mass) of a substance that contains a hydrogen ion(H+) or a hydroxide ion (−OH−). Acids are proton donors, while bases are proton acceptors. Gram equivalent weight is defined as the mass in grams numerically, which is equal to Equivalent Weight. The equivalent weight of elements having more than one valencies is variable. Like Sulphur has 2, 4, […]
