between sodium thiosulphate (thio) and hydrochloric acid. Hydrochloric Acid + Sodium Thiosulphate "" sodium chloride + water + sulphur The reactants are both colourless‚ but one of the products‚ sulphur‚ is yellow‚ so we can use this fact to follow the rates of reaction. I am going to investigate how the concentration of the acid effects the speed of the reaction.

Modern methods of food production have altered radically from processes used in the past. Many food producing companies have invented their own improved techniques of cooking. Most of these procedures contain numerous different forms of chemical additives and one of the newest chemical substances that will enhance food flavor is monosodium glutamate (MSG). Even though it has no taste of its own‚ it intensifies considerably the taste of a wide variety of food as well as revealing flavors that could

How did the amount of Sodium Citrate‚ an anticoagulant‚ added to a Calcium Chloride solution affect the volume of the clots formed when a sodium alginate solution‚ a blood simulation‚ was introduced? Mackenzie Keesor (Fall Semester 2017-2018) Purpose The purpose of this experiment was to observe the differences in the formation of simulated blood clots when different amounts of sodium citrate‚ an anticoagulant‚ was added to the coagulation process‚ which would help gain information about the process

INTRODUCTION Sodium hypochlorite is considered one of the most efficient irrigant in endodontics 1-4. Due to its antimicrobial‚ tissue dissolving properties and low cost‚ it is one of the most widely accepted irrigant in Endodontic practice 5-8. Sodium hypochlorite as a solution is relatively an unstable compound. On exposure to organic compounds‚ heat‚ light‚ air and metals‚ the available chlorine ions reduce and there is subsequent loss of tissue dissolving and antimicrobial properties 9-10. Recent

unlike at the taste. By adding flavorings‚ it can be used by everyone in the family. D. Definition of Terms • Sodium Bicarbonate – Baking Soda • TRPM8 – Transient receptor potential cation channel subfamily M member 8 also known as the cold and menthol receptor 1‚ is a protein. TRPM8 is an ion channel‚ upon activation it allows the entry of Na+ (sodium) and Ca2+(calcium) ions to the cell that leads to depolarization and the generation of an action potential. This eventually

Clostridium Difficile People getting medical care can catch serious infections called healthcare-associated infections or HAI’s. One type of HAI which is caused by the germ Clostridium Difficile or C-Diff. In 2015 it was estimated almost half a million infections in the United Ststes‚ and 29‚000 died within 30 days of the initial diagnosis. Those most at risk are older adults‚ who take antibiotics and also get medical care. The CDC provides guidelines and tools for the healthcare population to help

must regulate is water; water is everywhere in our body and its balance is essential for proper body function. A very carefully regulated process is solute concentration. If there is a sudden increase in water which enters the extracellular fluid‚ sodium ions will then contribute less to the extracellular solute concentration as the ratio between water and solute has now changed. Osmolality is the amount of solute in a kilogram‚ hence the osmolality in the extracellular space has also decreased.

They are very reactive metals and do not occur freely in nature. Alkali metals are malleable‚ ductile‚ and are good conductors of heat and electricity. Alkali metals can also explode if they are exposed to water. The Alkali metals are: lithium‚ sodium‚ potassium‚ rubidium‚ cesium‚ and francium. Lithium The mineral petalite‚ which contains lithium‚ was discovered by a Brazilian scientist named Jose Bonifacio towards the end of the 18th century. Then in 1817‚ lithium was discovered by Johan August
