The objective of this experiment was to learn the process of recrystallization and how this process removes the impurities from a pure solid compound. The methods used to achieve this objective were also hot vacuum filtration in order to remove suspended solid impurities‚ and isolating the pure acetanilide. In the next lab‚ percent recovered was obtained through weighing the acetanilide sample as well as comparing its melting point range. In this experiment‚ the sample‚ acetanilide was weighted

Your “Fantastic Voyage!” is continuing. You are still a video reporter piloting a mini-sub that has been put through a miniaturization process making you and the sub only 8 microns long. This time‚ you have been swallowed by a 55 year old man eating a hamburger‚ french fries and a root beer. 1.For the first portion of the mission‚ you are to pilot your sub through the gastrointestinal tract to monitor the digestion of his meal.

something that has made a huge difference in people’s lives is the water filtration system(s). NASA first made it to be used on the space station or in a spacecraft‚ and since then the water filtration system is a must-have in any place in the world. NASA showed amazing ingenuity to control bacterial contamination in space‚ and because of that‚ we have learned how to control pollutants in water here on earth. We see water filtration systems more than we think‚ and it allows us to enjoy a healthy lifestyle

barium sulphate‚ BaSO4‚ by gravimetric analysis. For the experiment‚ a dilute solution of barium chloride was slowly added to a hot unknown sulphate solution slightly acidified with concentrated HCl. The precipitate is then filtered off by suction filtration‚ washed with water and dried in the oven at 150 degree Celsius for about half an hour and cooled in the desiccator‚ and weighed as barium sulphate and the percentage of sulphate was calculated from the weight of barium sulphate.

Based on the articles “Issues and New Directions in Global Consumer Psychology” by Mashewaran and Shavitt‚ and “Simulating Market Dynamics: Interactions Between Consumer Psychology and Social Networks‚” by Janssen and Jager‚ scholars portray consumer psychology in a different light based on how they attempt to create a successful marketing communication message.

the mixture flask. This will stop the water escaping as it touches the cold surface of the condenser. The condenser has a permanent water flow going in and out and this is why the water drip back to the flask as it touches the cold surface. Vacuum filtration was used isolate the solid from the liquid-solid mixture after the sulphuric acid is qqadded and that the precipitation has occurred and that the pH is down to 2. Recrystallization was then used to purify the salicylic acid formed earlier. Boiling

Filter Innovations Inc. Filter Innovations Inc. (FII) was created by John Dragasevich in 1992. It was based out of Toronto‚ Ontario and supplied small industrial water filtration systems and environmental products. It focused mostly on projects that required processing below 1 million litres per day. This was because competing companies were more interested in projects that required processing above 1 million litres per day. Problem Statement The problem Dragasevich faces with FII is that
