Filtration

Interaction of concentrated nitric acid and sulfuric acid generated nitronium ion which is electrophile. And methyl benzoate nitration is one of electrophilic aromatic substitution. Nitronium ion will reacts with protonated intermediate at the meta position. After NO2 substituted, it becomes arenium ion intermediate. Then, the remained product HSO4- will attack hydrogen then transfer the proton to methyl 3-benzoate. In the experiment, students placed around 12 drops of concentrated H2SO4 in…

If I became stranded on an island the four items I would choose to bring is a machete, a water filtration device that could both filter fresh water and convert saltwater into freshwater, a sleeping bag and another person, who would also bring their four chosen items with them. The features I would like the island to have is that there is an abundance of trees, many animals of all sorts, different terrains and it would be nice if it were a larger island. One of the item’s I would choose is a…

passengers” (McGuire). One passenger with H1N1 spread to 17 people in that flight and was spread to 22 people during that flight even though the air filtration system is supposed to eliminate these. The reason why these illnesses are being spread easily through a plane is because these pathogens are not given the chance to go through the filtration…

1.73 m2 -the total renal blood flow is 1200 mL/min -total renal plasma flow ranges 600 to 700 mL/min GLOMERULAR FILTRATION Glomerulus- consists of a coil of approximately eight capillary lobes (capillary tuft) -located within Bowman’s capsule - serves as a nonselective filter of plasma substances (MW less than 70,000) Several factors influence the actual filtration process 1. cellular structure of the capillary walls and Bowman’s capsule - three cellular layers: *the…

without touching directly to the sand. The mixture was then boiled gently at the boiling point for 10 minutes, removed from the heating, and settled for a minutes. The solids were then left behind while the liquid was transferred into the pressure filtration assembly…

Stoichiometry lab was to determine which of the two possible iron sulfate compounds formed when reacting aqueous copper(II)sulfate with solid iron metal. The techniques used in this lab were weighing by difference, quantitative transfer, and vacuum filtration. At the end of the experiment it was found that iron was the limiting reactant and iron(II)sulfate was a product of the reaction between 7.0002g of copper(II)sulfate and 2.0101g iron metal which produced 2.3037g of copper product with a…

recrystallization is to have the minimum solubility (better no solubility) at room temperature but when we heat up the solvent we want the maximum solubility. I tried to get less sand in my first filtration and get all of the crystals from my flask. A source of error might’ve been leftover sand (even after filtration) And the amount of solvent that we had to add to our solution should be right to get the right result. So I added hot water step by step until I got the crystals that I wanted.

Residential reverse osmosis systems have been around for the last thirty years or so. When people first started to realize that their drinking water might be contaminated, they turned to existing reverse osmosis technology to treat their water. At first it seemed like a great way to purify your water. Yet, over the years, the popularity of residential reverse osmosis systems has steadily decreased. There are three reasons for this. The first reason is the recognition that reverse osmosis strips…

First, 1.32 g of isoborneol was mixed with 1.00 mL of glacial acetic acid. The solution was heated to 50° C while 1.70 mL of NaOCl added. Then 15.0 mL of NaOCl was measured into a separatory funnel and added dropwise to the solution for 10 minutes. The flask was sealed while heating and stirring continued. NaOCl in the solution was tested every five minutes using starch-iodide paper for 30 minutes. After 10 minutes, 2.0 mL of NaOCl was added. A total of 6.0 mL of NaOCl was added over a 20 minute…
