For the third lab we did a pH scale based lab. We had 13 solutions and we had to find the meter, paper pH level, AVG and ANB.
Before that I had tap water in a beaker and used a dropper to add 10 drops of Bromothymol blue in it then blew into a straw. We blow out carbon and water is an acid therefore the solution is carboniacid, it was blue but went from basic solution to a acidic solution (yellow) by producing carbonic acid from my breath!
Solutions: H2O, Buffer, Ammonia, Vinegar
Solutions: Lemon Juice, Coffee, Rolaid, Detergent
Solutions: Diet Coke and Lemon Low Concetration
Solutions: Baking Soda, Bleach and Coke
The final inputs of our lab!
