affinity for teaching‚ it fails to fully incorporate my interests in the sciences and their applications. Being a nurse practitioner would. As a nurse practitioner‚ I would be able to teach others more than just the basics of biology or how to do stoichiometry in chemistry. Instead‚ I would pass on my more applicable knowledge of health promotion and disease prevention‚ thus educating patients about their own health and teaching them how to take care of themselves.

constituent into another compound containing that constituent and measuring the percentage of sulphate in the new compound to determine the percentage of sulphate in the previous compound. This experiment also demonstrates the concept of stoichiometry. Stoichiometry is the determination of the proportions in which chemical elements combine and the mass relations in any chemical reaction. Also known as mass analysis‚ gravimetric analysis is used to determine an analyte by selective precipitation

Reaction Mechanisms The mechanism of a chemical reaction is the sequence of events that take place as reactant molecules are converted into products. Introduction The study of kinetics includes very complex and sophisticated reactions that cannot be analyzed without a proposed mechanism‚ a series of steps that a reaction takes before reaching the final products. Reaction mechanisms are step-by-step descriptions of what occurs on a molecular level in chemical reactions. Each step of the reaction

The purpose of the Weak Acid Dissociation experiment is to determine the dissociation constant of a weak acid experimentally by using acid-base titration with a strong base and stoichiometry. An acid-base titration is a method by which a basic (or acidic) solution of unknown concentration is reacted with an acidic (or basic) solution of known concentration. (1) The pH in acid-base titration is measured using a pH meter or color changing indicator‚ such as phenolphthalein‚ as the known solution is

PORTLAND CEMENT Chemical composition. Portland Cement is made up of four main compounds: tricalcium silicate (3CaOSiO2)‚ dicalcium silicate (2CaOSiO2)‚ tricalcium aluminate (3CaOAl2O3)‚ and a tetra-calcium aluminoferrite (4CaO Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols‚ these compounds are designated as C3S‚ C2S‚ C3A‚ and C4AF‚ where C stands for calcium oxide (lime)‚ S for silica‚ A for alumina‚ and F for iron oxide. Small amounts of uncombined

Abstract. This report is about how to standardize a Sodium Hydroxide (NaOH) solution by titrating it with pure sample of Potassium acid Phthalate (KHC8H4O4). This experiment has two sections. The first section is to standardize the Sodium Hydroxide by titration. Three sample of 0.7 – 0.9 g of solid KHP are place into each of the three numbered Erlenmeyer flasks. 50 ml of distilled water are added to each three of it from graduated cylinder and constantly shake it until the KHP solution are completely
