To investigate the results of the different amounts of sodium bicarbonate (2g‚4‚8g)‚when put in the baking process to produce cupcakes‚obtained by the change of height of a cupcake measured by a ruler‚when baked at 180 degrees celsius for 20 minutes when measured with a ruler. Research question: What will be the result of adding different amounts sodium bicarbonate (2g‚4g‚8g) in a standard (vanilla) cupcake ‚when they are baked at 180 degrees celsius over a period of 20 minutes using an oven thermometer

The Effects Sodium Chloride has on pond water Introduction Ponds are depressions in the ground that fill with water from either run offs or melting snow or rain fall from many different weather changes. There are two types of ponds permanent and temporary. Ponds tend to be much smaller in size and are usually only six to ten feet in depth. This differs from a lake because the size of a lake is much larger and is much deeper. The temperature of a pond is usually the same from top to bottom and

ABSTRACT OBJECTIVE To learn the concept of separating organic compounds by utilizing the concept of acid/base chemistry in so that separation can be done. INTRODUCTION Using acid base chemistry in the separation of substances can be a quite useful technique in organic chemistry. A basic extraction can be carried out by applying a hot solvent such as water to a dry substance like coffee. This will allow for the extraction of caffeine and flavor from the coffee beans. Acid base chemistry can be

Title: Preparation and Standardization of a Sodium Hydroxide Solution Objective/Purpose: The objective of this experiment will be the standardization of sodium hydroxide using potassium hydrogen phthalate by the titration method. Introduction: The concentration of solutions can be reported in terms of molarity and normality. Molarity is equal to: HCL‚ HBR‚ H2SO4‚ HNO3 M = mol Solute (mol) (Monoprotic) (Diprotic) _______________ V(L)g solutions (L)

covalent compound because both hydrogen and iodine are nonmetals. 6) Why would the bulb light up when placed in an aqueous solution of sodium chloride but not in a solid sample of sodium chloride? In a solid sample of sodium chloride‚ sodium and chloride are bonded together ionic and so there aren’t any free electrons to support the flow of electricity. When sodium

Experiment 7 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction: The student will perform the experiment in order to find the percent yield by using the theoretical value found using the balanced equation for sodium carbonate as well as sodium bicarbonate. The objective is to stabilize the substances by titrations and finding the percent yield when all the data is collected. The purpose of this procedure is so that the student will get better understanding of stoichiometry

Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour

The chemical equation for Thiopental Sodium is C11H17N2NaO2S. First synthesized in 1935‚ the proper name for the drug is Thiopental Sodium it also goes by Sodium Pentothal but that is actually a trademark of the drug ’s manufacturer‚ Abbott Laboratories. A yellow water-soluble crystal‚ it is classified as an ultra-short acting barbiturate‚ a type of drug that depresses the central nervous system‚ slowing the heart rate and lowering blood pressure.
