From the observations list I came up with these Procedures:
1. Mix water, and BTB, record observations
2. Mix water, BTB, and Snail in different beaker, record observations
3. Mix water, BTB, Elodia, and an aquarium plant in seperate beaker, record observations.
4. Mix water, BTB, Snail, Elodia in seperate beaker, leave in dark for 3 hours, then record observations
Explainations:
1. Mixing the water and BTB lead to blue/green because there wasn't any thing Acidic added to it.
2. the #2 mixture lead to a yellow discoloration because the snail added an acidic touch to the mixture.
3. the #3 mixture stayed blue because of the additive of elodia, and the plant must of been a basic sort of ingredient that didn't react with the BTB.
4. the #4 mixture stayed blue/green in the light because i don't think that the snails acidity had enough time to counter act the elodia. But when the sample was left in the dark for 3 hours, I believe that the amount of time was enough to let the snail do its thing and let its' acidy take over the elodias' basic properties and thats why the end result was a yellow colored mixture.
Questions:
1. Would the samples be different if all of them were left in the dark for three hours, not just sample #4?
2. What other items of acidic quality would we be able to use besides a snail? And also, what if we had tried to put more of the elodia or plant inside the beaker in order to bring up a mixture so strong that the snail couldn't over power, no matter how much time.
3. If the mixture comes out strait blue is it more of a basic Ph? Is yellow more of an acidic Ph?
At first i thought "man, this lab doesn't make sense!" But now after looking at the list of FACTS on the front, I have a better understanding of how things are.
