pH & Phosphates

Problem:
How many ppm of pH, Nitrates, and phosphates are there under the Chimacum Creek bridge.

Hypothesis:
We thought that the results were going to be bad because the way the creek looked.

Experiment:
Materials-

pH
1. Octet comparator
2. Test tube
3. 5.0mL creek water
4. Indicator solution

Phosphates
1. Test tube
2. 1.0mL of creek water
3. Pipette
4. 1.0mL phosphates acid reagent
5. 0.1g phosphates reducing reagent
6. Nitrates-N& Phosphates comparator

Procedure-

pH

1. Fill test tube to the 5.0mL of the sample of water.
2. Add indicator solution according to octet comparator.
3. Cap and mix.
4. Insert test tube into Octet Comparator to match color to color standard.

I noticed that our results are really good it was a 7 just right for fish to breathe.

 

Phosphates

1. Fill test tube to 10mL line with sample of water.
2. Use the 1.0mL pipet to add 1.0mL of phosphates acid reagent. Cap and mix.
3. Use second 0.1 spoon add on level measure of phosphate reagent. Cap and mix. Until dissolved. Wait 5 min.
4. Remove cap. Place into Nitrate-N and Phosphates comparator with Axial Reader. Match the color to the sample.
I noticed that the results for the phosphates were good too really good.

ph is 7

***************************	***************************

pH was 7 and the Phosphates was less than 0.2

Conclusion:
Our hypothesis was wrong because our results were really good. The pH was just right for fish to breathe and the phosphates was good because that means there is not a lot of bad stuff in the water. We got less than 0.2 ppm.

The results were good pH was 7 ppm and the phosphates was less than 0.2 ppm so there wasn't any bad stuff in the water.

I learned the results were good the pH was just right for the fish to breathe not acidic or basic and the phosphates was less than 0.2 that means there is very little bacteria in the water from sewer run offs.
We must of done it right because all the scores were good but we might have put too much of something in the phosphates because it was lighter than the color stander a chemical could have lightened the color.
I would take 3 different samples in 3 different places then compare the results to see what place is the best because I think that the water gets better down steam because it is getting filter through rocks.

I think I would watch out so I don't knock down anything or count the drops of stuff I was sappost to put in.
