Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

Lab O6 – Equilibrium Lab Application Purpose: An introduction to the qualitative aspects of chemical equilibrium. Starting with a reaction at equilibrium‚ one will change the concentration of various ions present in the equilibrium‚ and record the states of the changing equilibrium through observation. Theory: Equilibrium- the point at which a solution has become perfectly saturated; when their forward and reverse reaction rates are equal Concentration- a measurement of how much solute

The importance of calcium and phosphorus is that they play a role in the body and their role is to build bones and teeth this is because they allow rigidity to the structure of the bones and teeth. This is because bones are continuously being rebuilt with new bone being formed and also teeth as well but at a slower rate but this is why calcium and phosphorus is needed and is important. The role of calcium is that it circulates blood and it also helps blood clot in other body tissues and also plays

Investigating the Properties of pH The manufacture’s claim is that Sensodyne toothpaste micro hardens tooth enamel to help protect against the effects of acid wear‚ helps stop the twinges of pain from sensitive teeth formulated with low abrasivity‚ neutral pH and gentle yet effective cleaning system. To find out if the manufactures claim on Sensodyne toothpaste is the correct level of pH. I expect the Sensodyne toothpaste to be a neutral pH level as the manufactures claim that this products

Long Run Equilibrium (A) Firm and Industry: A competitive market is made up of a large number of firms with complete freedom of entry. Such firms together are called competitive industry. An industry can be defined as a group of firms producing homogeneous products with freedom of entry and exit and which earn only normal profits. Hence the concept of an industry is applicable only under competitive conditions. There is no fixed size of an industry though the analytical stability of an industry

ceiling create shortage. How to overcome it? According to the book “Economic Theory in the Malaysian Context”‚ the definition of price ceiling is a legally established maximum price a seller can charge. It means that the price is lower than the equilibrium market price and it cannot go above the ceiling price. The reason that government imposes ceiling price on item such as beef‚ flour‚ sugar and many more is because to ensure that consumers are able to buy these goods at a reasonable price thus prevent
