  • Bromocresol Green Indicator Bromocresol green (BCG) is a dye that is used in chemistry as a pH indicator in acid-base titration and in thin-layer chromatography staining solutions to visualize acidic compounds. The aqueous indicator solution of bromocresol green is yellow below pH 3.8 and blue above pH 5.4. It is also important in clinical diagnosis […]
  • What are Metals? Metals in chemistry are chemical elements that are good conductors of heat and electricity and form positive ions by losing electrons. On the basis of properties, 118 chemical elements present in the periodic table can be divided into two main groups metals and non-metals. Metal is a substance that is produced naturally […]
  • What is Water Electrolysis? Water electrolysis is the process where water can split into hydrogen (H2) and oxygen (O2) through the application of electricity or electrical energy. Most of the hydrogen gas produced or used worldwide is created through the electrolysis of water. The Dutch merchants Jan Rudolph Deiman and Adriaan Paets van Troostwijk first represented […]
  • What is Polymerase Chain Reaction? Polymerase chain reaction (PCR) in biology and chemistry is a laboratory technique used for making millions to billions of copies of a specific DNA molecule. PCR is a cell-free amplification technique used for synthesizing multiple copies of any DNA molecule for medical, forensic, and biological research. Polymerase chain reaction can […]
  • What are Biopolymers? Biopolymers are natural polymers or polymeric biomolecules produced by the cells of living organisms. They are monomeric units that are covalently bonded to form larger molecules. Deoxyribonucleic acid (DNA), ribonucleic acid (RNA), protein, and carbohydrates are the most common biopolymer materials produced in the cells of living organisms. The name biopolymer originates […]
