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: […]

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 […]

Transpiration is the movement of water from the plants into the air. But if you are asked to define what is transpiration, you can say it as “The loss of water in the form of vapor from the aerial parts of the plants into the atmosphere.” In spite of the loss of water by transpiration, […]

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 […]

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 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 […]

Potentiometric titration is a method of chemical analysis. This technqiue relies on the measurement of electromotive force (EMF) of a solution using a set of indicator and reference electrodes. The potential or EMF of a solution depends on the nature and concentration of the ions of the test substance. The EMF or potential is measured […]

The soil is home to many organisms of the entire animal kingdom. These include microorganisms, worms, insects, amphibians, reptiles and even mammals. These include Bacteria Protozoa Fungi & Algae Nematodes Annelids (earthworms) Molluscs Insects and orthopods like ants, beetles Amphibians Reptiles like lizards, snakes. Mammals like rodents Organisms living in the soil in detail Organisms […]

High performance liquid chromatography finds widespread application in analytical chemistry and biology. There are different types of HPLC like 1. Based on modes of chromatography : a) Normal phase mode b) Reverse phase mode 2. Based on principle of separation : c) Adsorption chromatography d) Ion exchange chromatography e) Ion pair chromatography f) Size exclusion […]
