remain after the reaction comes to an end. An understanding of chemical equilibrium and how it can be manipulated is essential for anyone involved in Chemistry and its applications. Iron-Silver Equilibrium In the first phase of the experiment‚ iron sulfate was mixed with silver nitrate‚ and the reaction produced solid silver and iron nitrate‚ which is formally written as Fe2+ (aq) + Ag+ (aq) ⇄ Ag (s) + Fe3+ (aq) It has a net equation of: Fe2+ (aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) The mixture was then

differ from those used previously for solid products. The water that forms during the reaction will be separated from the ester along with the wash liquids. Any traces of water that remain are then removed by a drying agent‚ either magnesium sulfate or sodium sulfate. Because isopentyl alcohol has a lower boiling point than that of isopentyl acetate‚ and the by-products have higher boiling points‚ it should be possible- in principle- to remove the alcohol and by-products from the ester by distillation

Along with other minerals‚ vitamins are substances that a person can find in the food they eat. There are nutrients which are essential to the body‚ because all metabolic reactions in the organism happen thanks to their presence. One of the greatest things about vitamins is that they can be taken in both pill and liquid form. Experts in nutrition consider liquid vitamins to be a remarkable breakthrough in the domain. This is one of the reasons which may explain the lately outburst of liquid supplement

Consturction Material EGC 1131 Assignment 1 Question 1 (a) A significant tendency for large and fine particles in a concrete mix‚ separate among each others. Segregation is caused by * Too wet mix‚ extremely high workability or less cohesive mixture causes the mixture unable to hold heavy aggregate * Dropping from excessive height * Over compaction of fresh concrete. Two methods to minimize segregation in fresh concrete: * Adequate workability is enough. * Don’t over

Sulfination Units Sulfination is the introduction of sulfonic acid into an organic compound. The usual sulfinating agent or sulficant is concentrated sulfuric acid but‚ sulfurtrioxide‚ chlorosulfonic acid‚ metallic sulfates‚ and sulfamic acid are also occasionally used. The name sulficants comes from these molecules moving to the surface of a liquid or to an interface between two liquids and changing the properties of the surface. However‚ the nature and properties of sulfuric acid‚ makes it

To begin the experiment‚ the reaction apparatus was assembled (as shown in Figure 1 below from the lab manual) consisting of a 3.0 mL conical vial charged with p-cresol (80uL from Eppendorf pipette)‚ 25% aqueous NaOH (130uL)‚ and a spin vane. The solution was mixed thoroughly and tetrabutylammonium bromide (9mg) was added along with n-propyl iodide (75uL) and it was equipped with a flask with a water reflux condenser. The solution was heated (95-100°C) while vigorously stirring it. After 60 minutes

double displacement reaction in which sodium in sodium sulfate being more reactive‚ was replaced by barium from barium chloride and was able to form barium sulfate‚ a white solid pigment and sodium chloride 2. As barium sulfate is insoluble in water it was relatively easy to observe and interpret what was happening as the chemicals mixed 2. The formation of zinc yellow also involved a double displacement reaction 3. The addition of zinc sulfate to potassium chromate formed a yellow coloured solution
