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

The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

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

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‚

Hydrochloric-Acid Written By Kahlil Zione Date:02/02/05 Abstract: We observed the reaction between zinc and hydrochloric acid and recorded it in a table and learned wether the percentage of zinc is effected by the amounts of both substances added to the solution. Introduction The purpose of this experiment is to determine if the amount of zinc and hydrochloric acid will effect the percentage of the zinc in the out coming solution. We are reacting zinc metal with hydrochloric acid to produce
