AP Chemistry Chapter 17 Additional Aspects of Aqueous Equilibria Chapter 17. Additional Aspects of Equilibrium Common Student Misconceptions • • • • • Students often believe that the pH at the equivalence point for any titration is 7.00. In terms of problem-solving skills‚ this is probably the most difficult chapter for most students. Students tend to find buffers particularly difficult to understand. Students often forget to consider volume changes that occur when two solutions

D_____ J_____ CARBOHYDRATES LAB May 22‚ 2013 Pre-lab Questions 1. The water in test tube No. 1 is a negative control. No reaction is expected to occur because water is not a carbohydrate. Reaction by a negative control is evidence of contamination. 2. The color changes expected for positive test results are Benedict’s test: orange to brick red Tollen’s test: metallic silver Starch iodine test: blue-black 3. Identify each of the samples in Part 1 as monosaccharide

Submitted: June 10‚ 2015 Title: Observations of Chemical and Physical Changes Purpose: the purpose of this lab experiment is that I will be able to decipher the difference between a chemical and physical change. I will be about to tell whether a chemical change has occurred during the experiment or if it was a physical change and I will be able to answer why it is either one. Procedure: In the lab experiment‚ I mixed different types of chemicals with different background to see if there was a chemical
