Gravimetric analysis is a method of quantitative chemical analysis in which the mass of a compound is used to determine its quantity. This technique is particularly useful for determining the concentration of a soluble chloride, such as sodium chloride (common table salt). In this essay, we will discuss the general principles of gravimetric analysis and the specific steps involved in performing a gravimetric analysis of a soluble chloride.

The basic principle behind gravimetric analysis is the measurement of mass. In order to determine the mass of a compound, it must first be isolated from the rest of the sample. This is typically done through a process called precipitation, in which the compound is transformed into a solid that can be easily separated and weighed.

The specific steps involved in a gravimetric analysis of a soluble chloride depend on the particular chloride being analyzed and the desired end result. However, there are some general steps that are followed in most gravimetric analyses.

First, the sample is prepared by dissolving it in a suitable solvent. The solvent should be chosen based on the solubility of the compound being analyzed and the desired end result. For example, water may be used as a solvent for a soluble chloride if the goal is to determine the mass of the chloride.

Next, the precipitating reagent is added to the sample. This reagent is chosen based on the solubility of the compound being analyzed and the desired end result. For example, a soluble chloride may be precipitated as a silver chloride by adding a silver nitrate solution to the sample.

Once the precipitate has formed, it is allowed to settle to the bottom of the container. The supernatant liquid is then carefully decanted, leaving the precipitate behind. The precipitate is then washed with a solvent to remove any impurities that may have been present in the sample.

Finally, the precipitate is dried and weighed to determine its mass. This mass can then be used to calculate the concentration of the soluble chloride in the original sample.

In summary, gravimetric analysis is a powerful tool for determining the concentration of a soluble chloride. By following the steps outlined above, it is possible to accurately and precisely determine the mass of a compound, which can be used to calculate its concentration.

Cockroach: Excretory System Essentiale

Fat bodies are analogous to vertebrate liver. The ureters open into the cloaca and act as a urinogenital duct. With our affordable courses like Lakshya, Udaan and Arjuna and many others, we have been able to provide a platform for lakhs of aspirants. Only I and II are correct 3. Types of Nephridia Based on structure and location there are three types of Nephridia. Malpighian tubules are analogous to mammalian kidney. Only II is correct 2.

The filtrate moves towards the ileum. In Cockroaches, malpighian tubules perform excretion. Buldana Topic: Excretory System of Cockroach Class: B. Complete step-by-step answer: Cockroaches are insects belonging to the phylum Arthropoda, which are dark brown and inhabit the unhygienic places. The Malpighian tubules absorb nitrogenous wastes and water from the bodily fluid hemolymph to produce urine an excretory solution that flows through the rectum and exits the animal body. It's function is to collect the filtrate from the Glomerulus, passing it on to the Proximal Convoluted Tubules PCT's ; subsequently, to the rest of the Unit 13: Physiology of Fluid Balance - P4, P5, M3, D2 The physiological overview involves the kidneys processing blood by eliminating any excess mineral salts, urea and water as this provides homeostasis and it enables the body to work effectively. Excretory System of Frogs Frogs belong to class Amphibia of phylum Chordata.

It feeds on a wide variety of organic matter and lives in burrows made by swallowing and boring the soil. This insect is uricotelic. The oviduct and ureters in females open separately into the cloaca. After the reabsorption, the waste product passes to the rectum and is expelled out through the anus. Fat bodies are analogous to vertebrate liver. Each tube is fringed by glandular and ciliated cells that absorb and soak up nitrogenous waste products.

On respective pleuritis, one pair of them is located between the prothorax and the mesothorax, and the other pair is located between the mesothorax and the metathorax. Only II is correct 3. Uric acid is not found in earthworms. The network is the extension of the alimentary canal which helps in the absorption of water and solutes and also in the removal of the wastes from the hemolymph. Each segment except the first three and the last one contains pores.

Malpighian tubules are responsible for excretion. The first layer from inside out is the mucosa layer, which is composed of transitional epithelium. The remaining materials passes into the gut. It is made up of a glomerulus, which is where ultrafiltration takes place, and a renal tubule, which is where the filtrate is changed. The frog excretes urea. The Bowman's Capsule is part of a Nephron, which would be found in the Kidney. The structures in cockroaches that aid in excretion are as follows: i Malpighian tubules : Malpighian tubules attach to the midgut and hindgut junction.

The anus is subsequently used to discharge the filtered wastes. The latter is a small area that dumps tubular fluid into one of the six ampullae. Transverse commissures join the six longitudinal tracheal tubes, which are divided into two dorsal, two ventral, and two lateral tubes. Uric acid is the nitrogenous metabolic excretory product. The glomerular are small clusters of capillaries within the kidneys. In the proximal parts of the malpighian tubules water and other useful substances are reabsorbed.

Pharyngeal nephridia: Located in 4th, 5th and 6th segments, which lie on either side of the oesophagus, pharynx and paired bunches. Hence frogs are ureotelic. Liquid wastes, which collect in the body cavity, are excreted through these nephridial openings. II: Malpighian tubules are present at the junction of midgut and hindgut in the alimentary canal of cockroach. The tubules filter wastes out of the body by collecting them from the blood.

Their bodies are divided into head, thorax and abdomen. They lie freely in the haemolymph. In cockroach following structures help in excretion: i Malpighian tubules : Malpighian tubules are attached at the junction of mid-gut and hind-gut. This large number of the integumentary network located in the clitellar region is known as forests of nephridia. The number ranges from 200-250 in each segment, except in the clitellar segments in which they are present ten times more than the usual number.
