Acid and Base Titrations: Preparing Standardized Solutions Introduction: This experiment focuses on titrations of acids and bases. A titration depends on addition of a known volume of solution and is a type of volumetric analysis. Many titrations involve either acid-base reactions or oxidation-reduction reactions. In this experiment we do one of each. We monitor the pH of the reaction with the use of a color indicator. We also learn about the standardization of bases (NaOH) and acids (HCl) which

Crystallization of Benzoic Acid Purpose: The purpose of this experiment is to purify benzoic acid by crystallization. Procedure: 1. 0.5g impure benzoic acid was placed in a 50mL Erlenmeyer flask. 15mL of water was added and the mixture was heated to a boil on a hot plate. 0.5mL of water was added to the flask‚ while swirling the flask. The mixture was boiled until the benzoic acid completely dissolved. The total volume of water used was recorded. The black solid that remain in the dissolved

Decorating a Kid’s Table for Christmas No matter how old you are I am sure you can remember being shoved over to the children’s table at Christmas. This “special” table was usually set with some inedible arrangements and included your very annoying cousin whom you wanted to throttle before you even finished the blessings!! Special was a good word that mom came up with to describe the children’s table. We had one cousin poking you‚ yelling and throwing food‚ another would have his nose picking fingers

Table Tennis History Like many other sports‚ Table Tennis began as a mild social diversion. It was probably played with improvised equipment in England‚ during the last quarter of the 19th century. Though Table Tennis evolved‚ along with Badminton and Lawn Tennis‚ from the ancient game of Tennis (also known as Jeu de Paume‚ Real tennis‚ Court Tennis or Royal Tennis)‚ the game was developed after Lawn Tennis became popular in the 1880s. Game manufacturers tried many experiments to market
