Lab 5.1 Testing Acids & Bases

We did a lab which utilized chemical indicators to determine if a solution was a acid or a base.
I can analyze evidence to make judgements. In the first part of the lab we had to use indicators to see what color a solution would turn a acid, neutral, and base solution. When filling out this part of the lab, I made the observation that red litmus paper would only turn blue once in a base, and that phenolphthalein turned solutions colorless when used, I held onto this knowledge to further quicken my work. I was able to see patterns with how indicators reacted to solutions, for example, knowing that the solution turns colorless in phenolphthalein and yellow in bromothymol blue, it must be an acid. Recognizing patterns allowed me to make educated guesses on the resulting answer of whether it is an acid, base, or neutral. Lastly, analyzing my lab answers allowed me to streamline the process of my “discussion question” work sheet. In conclusion, analyzing evidence allowed for me to make educated judgements on how I wrote my answers in both the lab report and discussion question.
