Mike Vitale Professor Golden CHE*111 7 April 2008 Determining Ph: Acids and Bases In this lab we used three different liquid indicators and two pieces of litmus paper to determine the pH of eight different mixtures. Different reactions with different indicators will determine a range of numbers in which the pH can fall. If all of our observations are recorded accurately then we should be able to determine the pH of each of the mixtures. In turn we can tell which mixture is an acid and which mixture is a base. Data: Litmus Paper - If the litmus paper changes from blue to red then the pH of the mixture is less than 5.2. If it changes from red to blue then the pH is greater than 8.1. If there is no change then the pH is between 5.2 and 8.1. Methyl Orange - If the methyl orange changes red then the pH of the mixture is less than 3.1. If it stays orange then the pH is between 3.1 and 4.4. If it changes yellow then the pH is greater than 4.4. Thymol Blue
