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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
