Unformatted text preview: Emily Bissel MS#1116 Lab Partner: Becca Angell September 7, 2007 Thurs. AM Color Changes Introduction: The purpose of this experiment is to try to determine the ideal temperature and concentration to create a reaction between solution A and solution B in 30 seconds. To determine this, various concentrations of both solutions were combined and timed to find the varying reaction times. Temperatures were both raised above room temperature and lowered below room temperature to find the effect of temperature change on the reaction. Results: When solution A (potassium iodate) was combined with solution B (acidic starch solution), the mixture turned a dark blue color. When the solution was left at room temperature, it made the reaction time very close to 30 seconds. When the solutions were combined in a 2:5 ratio, the reaction time was also very close to 30 seconds. By were combined in a 2:5 ratio, the reaction time was also very close to 30 seconds....
