most simple bath bomb recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide (CO2) gas. This gas

Acid-Base Titrations February 21‚ 2013 Abstract: With the given volume measurement of KHP and NaOH‚ the students experimented to calculate the mass of unknown acid and its equivalence point using a method called titration and titration curve. The known volume of an acid solution would be titrated by slowly adding drops of solution into NaOH‚ and the volume of base needed to react with the acid is measured throughout. By using those data‚ the students are able to find what they

TWO-BASE EXTRACTION OF BENZOIC ACID‚ 2-NAPHTHOL‚ AND NAPHTHALENE FROM UNKNOWN SAMPLE # 131 Douglas G. Balmer (T.A. Mike Hall) Dr. Dailey Submitted 11 July 2007 Introduction: The purpose of this experiment was to separate a sample of benzoic acid‚ 2- naphthol‚ and naphthalene of unknown proportions using a two-base extraction method. The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different

puts it‚ “Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules”. Proteins are “Macromolecules that contain nitrogen as well as carbon‚ hydrogen‚ and oxygen”(Miller‚ Kenneth R.‚ and Joseph S. Levine 48). Macromolecules are exceedingly large molecules that can be made up of several lesser molecules called proteins. These proteins are made up of numerous amino acids‚ which are “Compounds with an amino group (-NH2)

Who Took Jerell’s iPod? Lab Purpose: Standardized Tests The purpose of testing the organic nutrients (vegetable oil‚ glucose‚ starch‚ powdered egg white) with each of the different indicators (brown paper towel‚ benedicts‚ iodine‚ biurets) was to determine the color it would turn with positive traces of the nutrient. The purpose of testing just the Distilled H2O was to determine the color it would turn with negative traces. Nutrient in the Different Foods The purpose of testing each of the

____________________________________________________________ ____________________________________________________________ ______ This lab was basically about finding the percentage of acetylsalicylic acid in an aspirin tablet. First‚ the base was created‚ which was made out of 1.00 g of NaOH and D-water. Then the buret was attached to the clamp on the ring stand and the base was poured into the buret. After that‚ one by one‚ an aspirin tablet was dropped into an Erlenmeyer flask filled with 50 mL of D-water

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment‚ why they hold the different properties that depict them‚ how their atomic structure may be fathomed‚ and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire‚ the science of Organic chemistry did not develop until the turn of the eighteenth century‚ mainly in France at
