| Separation of Nitrophenols | | | | Abstract: Using a micro scale steam distillation we separated ortho and para-nitrophenol from a mixture that was already made. After the para and ortho were separated we measured their melting points and compared it to the literature values for purity. For ortho-nitrophenol we had 60% recovery and for para 160% recovery. Our melting point ranges were ortho: 45-46°C and para 64-95°C. Introduction: Nitration: In phenols‚ -OH group strongly

Donald Trump‚ our elected president promised to make America great again. He promised to do many things‚ some of them seem possible to fulfill‚ others are unlikely to happen.

Chem 1211L Mrs. Amy Cook February‚ 9 2011 Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve

1. The body needs six basic nutrients: carbohydrates‚ proteins‚ fats‚ vitamins‚ minerals‚ and water. Each one helps the body carry out different functions. To start off‚ carbohydrates are a group of compounds that includes starches‚ celluloses‚ and sugars. Carbohydrates provide the body with calories along with ample sources of vitamins and minerals.

The physical world of course is real‚ how else would we feel pain

This flask was placed in a water bath on a magnetic stirrer. 3 mL of of 6% aqueous sodium hypochlorite was slowly added to the flask while maintaining a temperature below 30 degrees celsius. After thirty minutes a Starch/Iodine test was conducted to test for excess sodium hypochlorite‚ the strip did not change color so an additional 0.5 mL of reagent was added and allowed to mix for five more minutes. This process was repeated
