The lab was to include a purpose‚ procedure‚ data/observations‚ all reactions and side reactions written out with qualitative data beneath each product and reactant except H20‚ and a summary. The purpose of this experiment is to observe the qualitative aspects of a series of reactions involving copper. Procedure 1.Measure about 1g of solid copper. 2.Place Cu in Erlenmeyer flask and place flask under fume hood. 3.Add dropwise 15M HNO3 until solid copper is completely reacted. 4.Place flask

WHY I CHOSE THE PROJECT? This project has been chosen in view of increasing demand of milk and also due to higher expectations of good quality and low fat diet requirements of the people with better awareness. Also the requirement for such quality products is more acute today. In this project I have prepared soy milk from soyabeans and have compared the conditions of formation of good quality cow milk yogurt and soy milk yogurt. I have also tried to find the effect of temperature on the pH of

keeps you awake because of the presence of a chemical called adenosine‚ in your brain. It binds to certain receptors and slows the nerve cell activity when sleep is signaled. 5. Anaerobic fermentation is also a great concept which is present in the chemistry of everyday life. It is present in yogurt‚ breads‚ cakes and many other baking products. It is the multiplication of certain useful bacteria which increase the size of the food and make it more filling and soft. 6. Soap is formed by molecules with

| Desalinization of Water | | | Sara Reed‚ Myp2 | | Chemistry | | * Our world consists of 70% of water‚ from which‚ only 2.5% is fresh water‚ and 1% is drinkable water. Because of this low drinkable water rate‚ desalinization is a very important process which will help us provide a higher percentage rate. * Desalination is a process in which salt water is turned into fresh water‚ by extracting its water and minerals. Desalination is used on many ships and submarines

The Psychology/Neuro-chemistry of Music Part 1 of 2 I read the article posted by Michael Chanan earlier (How Music Changes our Brains) and was suddenly compelled to look into this. I’ve been a musician‚ of sorts‚ for some years and have always been curious as to why music affects people the way it does. I’m also partial to the odd read of a science magazine or two and so‚ I immediately turn to neurochemistry‚ not that I can say I’m an expert. I’ve been perusing ScienceDaily and TedTalks for

pH In chemistry‚ pH is a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7. pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity‚ aH+‚ in a solution. Universal indicator consists of a mixture of indicators such that there is a continuous color change from about pH 2 to pH 10. Universal indicator paper
