This paper is an analysis conducted on Nucleic Acids through a variety of tests specifically‚ Dische‚ Murexide‚ Wheeler-Johnson and Phosphate Tests in order to exemplify structural features of nucleic acids as well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide

The Global Recession and India The third quarter of 2007 saw a tremendous rise in the Indian stock market. It was amoment when every sector in India was booming‚ and the SENSEX‚ peaking at the20000 mark was the focus of every person in India. It was a moment when peoplewondered if they had lost the opportunity of a lifetime. What was then a hastydecision by most to make a quick buck‚ resulted in total pandemonium when thestock markets came crashing down all through 2008. It was in the last year

to Avoid that Causes Acid Reflux Problems in the digestive system should not be neglected. There are different possible digestive system disorders or diseases that are most often neglected by many people. The most common digestive problem is the acid reflux or gastro-esophageal reflux disease‚ mostly known as heartburn. Acid reflux affects different ages from infants to young children and adults as well. This disorder should be given special attention because it can lead to a more serious problem

Acid-base titration Aim To study the titration curve of a strong base-strong acid‚ strong base-weak acid and weak acid-strong base titrations Introduction Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant. When an acid and a base are present in a stoichiometric amount e.g. 1 mole HCl added to 1 mole NaOH‚ this means that the equivalent point has been reached in an acid-base system. The end point of an acid-base titration can be

Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts
