What is it? Folic acid is a water soluble B vitamin. It is used during pregnancy to prevent Neural Tube Defects (NTD’s). NTD’s are birth defects of the brain‚ spine or spinal cord (MedlinePlus). They can be fatal depending on how bad the injury is especially if it is to the brain. Folic acid works with vitamin B12 in the formation of red blood cells. Deficiency in both folic acid and vitamin B12 causes a certain type of anemia known as macrocytic anemia. Macrocytic anemia is a type of anemia that

Title: Estimation of Ascorbic acid Aim: To determine the ascorbic acid content of canned apple and orange juice To determine the volume of canned juice necessary to provide 75mg of Vitamin C Introduction: For the estimation of ascorbic acid‚ the method used involved the titration of the ascorbic acid‚ in the presence of a redox indicator 2‚6-dichlorophenol-indophenol (DCPIP) which acts as both an oxidant so as to oxidise the ascorbic acid to dehydroascorbic acid‚ and it acts as an indicator

Lewis Acids and BasesLewis acids and bases play an important role in chemical reactions because‚ except oxidation-reduction reactions‚ almost every reaction could be categorized as an acid-base reaction. Bases in water solutions show certain specific characteristics: bitter taste‚ feel slippery‚ and turn litmus paper blue. Acids in water solutions show these most common characteristics: sour taste‚ react with metals‚ and turn litmus paper red. The understanding of chemical reactions‚ such as acid

Proposal Report: Acid Violence in Bangladesh Background: Acid throwing on women and girls are on the rise in Bangladesh. Of all the gender-based violence directed at women‚ one of the most horrific is acid attacks. Acids are used to disfigure and sometimes kill women and girls. Reported reasons for the acid-throwing attacks include the refusal of an offer of marriage‚ dowry disputes‚ domestic fights‚ and disputes over property.. For the last few years‚ it has been on the rise in

Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as

Amino acids are important building blocks; they play an essential role in the formation of proteins and as intermediates in metabolism. Amino acids can serve as cell signaling molecules and can regulate gene expression. An optimal amount of amino acids is essential for health. There are over 500 amino acids‚ however only 20 are commonly found. Amino acids all have an amine functional group and a carboxylic acid functional group. They differentiate from each other in their side chains. Only 10 of

Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental level‚

CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds‚ and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined‚ resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt containing

Therefore‚ the experiment was performed to conduct quality control analysis on two commercial products to determine the amount of acid or base active in these two products and then compare the results to those of the manufacture. This was done through the preparation of standardized acid solution and standardized base solution‚ and through titration. The purpose of titration was to determine the concentration levels of the commercial products being used.
