What are buffers in chemistry? Types-examples and uses
Written by Adeel Abbas A buffer is a solution that can resist a change in pH. It is able to keep the solution’s pH stable by taking small amounts of acid and base. Specific and stable pH ranges are important for processes. Buffer solutions have a working pH range and capacity which dictate how much acid…

What is stp standard temperature and pressure in chemistry?
Written by Adeel Abbas Nominal conditions in the atmosphere at sea level are referred to as standard temperature and pressure, abbreviated as STP. The value is important for physicists, chemists, engineers, pilots, and navigators. In other words, the standard temperature is zero degrees Celsius (0 0C), which equates to 32 degrees Fahrenheit or 273.15 degrees kelvin.…

What is reflux in chemistry? A detailed guide
When we study organic chemistry, we see a reaction condition called reflux. Many students do not understand the meaning of reflux. Reflux is an important experimental technique in chemistry. Many organic chemical reactions take a long time to complete, so heat is applied in order to speed them up. High vapor pressures and low boiling…

Electromagnetic Radiations-Introduction, discovery and types
What are Electromagnetic Radiations? It is defined as a form of energy that is produced by the movement of charged particles through a matter or a vacuum. The magnetic and electric fields come at 90 to each other and the combined waves move to the other side of the field. Discovery of Electromagnetic Radiations? When…

What is the Difference Between Electron and Beta Particle? Electron vs beta particle
The main difference between an electron and a beta particle is that the electron is negatively charged while the beta particle can either be charged or not. The term elementary particles refer to particles with no structure. These particles cannot be separated into smaller parts. There are particles such as electrons and quarks. What is…
