The glass is one of the early discoveries of man. It was made out of molten sand. The uses of glass are indispensable, i.e., there will be no alternatives to it in some cases. Its applications to man include Kitchenware Eyeglasses and lenses Electronic Screens tv Microscopes for magnification Lights and bulbs Storage of specimens, […]

In humans and other animals, the transport of substances occurs due to circulatory system. In unicellular organisms, the transport within the cell occurs by cytoplasmic movements or by diffusion. But, transportation in plants is quite different. They have no circulatory system yet, the substances have to move to distant places. Water, plant growth regulators, minerals, […]

Gas chromatography is one of the widely used analytical tools. The applications of gas chromatography include Qualitative analysis Testing the purity of compounds To trace impurities Quantitative analysis Determination of a mixture of drugs Isolation and identification of metabolites Identification of compound mixtures. Qualitative analysis: Here the compounds in a given sample are identified. Qualitative […]

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 […]
