Introduction
Acids and bases were the fundamental concepts of this lab. Acids are molecules that donate protons or accept electrons.They also are a compound that increases the concentration of H+ ions when they are in water. They are at the lower numbers of the pH scale and range from 1-6. An example of an acid is a lemon. In comparison, bases are substances that accept or neutralize protons. Additionally, a base is a compound that increase the concentration of OH- ions that are present when with water. They usually react with acids to form salt and water. On the pH scale, they are on the higher numbers and are 8-14. An example of a base is bleach, the one used to clean out clothing. An Acid Base Titration is a chemical formula used to determine the concentration of a base or acid by neutralizing a base or acid using the known concentration of this base or acid. The analyte is the solution with unknown molarity while the reagent is the one with the molarity that is known. The analyte is identified by dissolving it into the reagent in small increments. The amount of reagent is written down once a change in the color of the …show more content…
When neutralized, the solution should have salts that are formed from equal weights of acid and base. An indicator is used in titration in order to determine the endpoint of the reaction. The end point is the minimum volume of titrant that must be added to cause a change. This endpoint is important as it helps determine the concentration of the unknown/variable. The equivalence point is the point of titration where the amount of reactants added matches the amount that was initially present in the tube. It can be determined by a color indicator as the solution will change colors at the endpoint and equivalence
