What system removes waste from the body and How

What system removes waste from the body

Kidneys are the vital organs which are involved in the excretion process. But there are also other organs which remove the waste from the body. These organs together constitute the excretory system as Kidneys Skin Lungs Liver Intestine All the above organs are involved in elimination. Elimination involves removal of waste from the body. Kidneys: […]

Factors affecting transpiration | Both Internal and External

Factors affecting transpiration

Transpiration is the loss of water from the plant surface into the atmosphere. The factors affecting the transpiration include Light Temperature Wind velocity Atmospheric humidity Atmospheric pressure Available water Leaf area Leaf structure Stomatal frequency Root-shoot ratio. Light: Light induces photosynthesis in guard cells  leading to sugar synthesis. The osmotic potential increases and the guard […]

Fluorimetry | Principle, Instrumentation and Applications

Fluorescence spectroscopy

Fluorimetry is a type of spectroscopy which measures the emitted radiation from a substance. This radiation is one which is emitted by the substance when the electrons transit from excited state to ground state. The principle of fluorescence spectroscopy: In UV-Visible spectroscopy, the excitation wavelength is measured. But, here the emission wavelength is measured. When […]

Azeotropic Distillation | With Two Examples and Applications

Azeotropic Distillation

You might have gone through different types of distillation techniques. Of them azeotropic distillation is quite interesting one. This method is used to separate azeotropic solutions. As per Wikipedia, an azeotrope is a mixture which cannot be separated by simple distillation. In general, most liquid mixtures can be separated by fractional distillation (FD). During the […]

Redox Titrations | The Experimental steps and Applications

Redox Titrations

Redox titrations involve oxidative reduction reactions. This types of titrations are quite common in usage next to acid-base titrations. As the name indicates, these redox titrations are used to analyze the reducing agents or oxidizing agent. The reaction involves the transfer of electrons, hydrogen or oxygen. The principle of redox titration: The test substance if […]
