A titration is a neutralization between a solution with a known concentration and a solution with a unknown concentration. A titration is used to figure out the unknow concentration. In this lab we used a titration to discover the concentration of the HCl used. The end point of a titration is a when a neutralization reaction in complete. We know when this has happened because of the indicator used which is commonly phenolphthalein changes the color of the solution. We know that it is complete when the solution is the lightest of that color it can be and the color stays past 30 seconds. My result were that the concentration of the HCl used was 0.1M.
Communication
My partner and I had to communicate this lab so that we could save time. This lab can be very long so my partner and I communicated as we worked so that we could split up task while keeping track of what was done. We further communicated when at the end of class we still didn’t have a clear result, so that we could come in during cent time to retry the lab.
