reaction will take place was ensured to be at room temperature. 4 drops of CuSo4 was added immediately after Beaker A was poured to Beaker B. The reaction was timed until it turned to blue. After the experiment, dispose all the Cu(II) solutions in inorganic waste jars and all the other solutions can be discarded in the sink with copious running water. RESULTS AND DISCUSSION Table 2.

In order to gain strong insight into the surface chemistry of silica we have perform a thorough literature search. Our goal is to identify the pioneer research performed on silica and silica supported catalyst. Particular interest lies in silica-water-cobalt and silica-alcohol-cobalt systems. This study is both on macro and micro level so that a complete theoretical base can be established. From this theoretical knowledge, key areas to look upon will be identified and a design of experiments will

Spectrophotometric determination of Ascorbic acid Concentration in an Unknown Solution Introduction: The naturally occurring organic compound with antioxidant properties is Ascorbic acid shortly referred as (AA). Normally the color of Ascorbic acid is white, but in some cases of impure samples it appears yellow in color. Ascorbic acid is solid in state. In water it dissolves well to give mildly acidic solutions. Ascorbic acid is one form ("vitamer") of vitamin C [1]. So, Ascorbic Acid (AA)

Purpose To examine the effect of H2SO4 on different percentage combinations of Zinc and Magnesium Hypothesis If more Magnesium is present, the reaction between H2SO4 and a combination of Magnesium and Zinc will reach a higher maximum temperature, because of the properties of Group 2 metals compared to that of transitions metals. Background The difference in properties between Group 2 metals and transition metals establish the basis for this experiment. Group 2 metals have two electrons in the valence

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eighteenth century, mainly in France at

The Alternating Chemical Reactions of the Copper Cycle *Nikko Baez and John Harling Chemistry 111 Course Section 475 Introduction: Copper has a very important biological and environmental significance, and is considered one of the most important elements all over the world. Within this experiment, copper’s ionic and elemental forms will be examined. This will be done by exposing copper to a series of chemicals and transforming copper into a nitrate, a hydroxide, an oxide, a sulfate, and then changing

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo, Ma. Cristina Joyce B. Department of Chemical Engineering, Faculty of Engineering University of Santo Tomas Espana, Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample, its alkalinity value, was stated in terms of mass of sodium carbonate. In doing so, any sodium

the removal and decomposition of harmful chemicals, the digestion of molecules in metabolism, and the synthesis of proteins, DNA, RNA, and many other organic molecules. Several key features about enzymes (which are similar to catalysts found in chemistry, only enzymes are organic molecules that are made of proteins or RNA) is their reusability; an enzyme will never be consumed in a reaction, rather it orients the molecules that would ordinarily perform the reaction correctly to minimize the energy
