Acid and Citric Fruit

Titration Lab How Much Citric Acid is in Your Soda? PURPOSE To determine the molarity (concentration) of citric acid (H3C6H5O7) in various different citrus flavored sodas. BACKGROUND PRINCIPLES Popular sodas all strive for a somewhat sour ('tart') flavor and manufacturers utilize acids to impart this taste. While there are a vast variety of different brands of sodas on the market, they can be broken into two main categories: dark or clear. This differentiation is not only a simple color...

Amino Acids

Amino acids are the building blocks of proteins. Amino acids bind together to form polypeptide chains, and these polypeptides fold and coil together into specific conformations to form proteins. There are 20 different amino acids, each amino acid consisting of four distinct partners. The first is a carboxyl group. A carboxyl group has very weak acids that are able to donate hydrogen ions to biological reactions. The second partner is the amino acid group. Amino acid groups act as the base which,...

Acids and Bases Lap Report

Acids and Bases Mirza Hasan Mammadov Acids and bases are really important in our daily day life. So let’s start with telling the definitions of them. Starting with acids, they are a substance which dissociates in water in order to produce one or more hydrogen ions. Also we can write H+ instead of hydrogen ion. Bases have the same definition, although the difference is that it firm hydroxide ions instead of hydrogen ions. We can write OH- instead of hydroxide ion. All alkali is bases but not...

Extraction of Benzoic Acid

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,...

Acid Base Titration Report

ACID BASE TITRATION OBJECTIVES 1. To demonstrate the basic laboratory technique of titration 2. To learn to calculate molarity based on titrations INTRODUCTION Molarity (M) or molar concentration is a common unit for expressing the concentration of solutions. It is defined as the number of moles of solute per liter of solution (or millimoles of solute per milliliter of solution). The concentration of a basic solution can be determined by titrating it with a volume of a standard acid solution (of...
