Answer:
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](https://img.qammunity.org/2020/formulas/chemistry/college/p5etwz00gsh1u5tullkg1cllw6v8wg8rnn.png)
So, the pH of the chamber 10 cm from the most acidic end:
![(12)/(35) pH/cm* 10 cm = 3.42](https://img.qammunity.org/2020/formulas/chemistry/college/3wd2k1wpk5fmss0w101f3dtob35kzam8sn.png)
The pH to be 10 cm from the most acidic end is 3.42.
