AP #2

This is a bit late, but here is my AP! I don't want to waste anymore time, so let's get into it.

For this AP, we had to construct a water filter, see its pH levels, and convert it into a logarithm. This was my process.

This was the water I used for my test. It's just water from my tap.

Next, here's my filter, it's pretty basic to be honest.

This is the test I did before the filter. As you can see, there is a bit of purple there.

This is the second test, after the filtering.

As you can see, both have purple hues to them, so the equations will be pretty much the same. 

On the scale the purple color represents about a 180. With this, we can make a ppm, or parts per million, equation. All we have to do is put the 180 as our numerator and put 1,000,000 as our denominator, and we have a ppm. Next, we convert that into a decimal, which would be 0.00018. Finally, we convert it into a logarithm, which when simplified, would be about -3.7! And then we're done!
