Question

You want to test the effect of pH on the distribution of Artemia in your 35cm long testing chamber. If you measure a pH = 1 at one end of the chamber and a pH = 13 at the other end, and the gradient distribution along the testing chamber is linear, what would you predict the pH to be 10 cm from the most acidic end?

Answer 1

The pH to be 10 cm from the most acidic end is 3.42.

Step-by-step explanation:

The pH at one end = 1

The pH at another end = 13

Length of the chamber = 13 cm

Change in pH with respect to length of the chamber from acidic end =
`x=(13-1)/(35 cm)=(12)/(35) pH/cm`

So, the pH of the chamber 10 cm from the most acidic end:

`(12)/(35) pH/cm* 10 cm = 3.42`

The pH to be 10 cm from the most acidic end is 3.42.
