a.
Answer to Problem 66PPS
Yes, he will worry.
Explanation of Solution
Given:
The safe standard for arsenic level is less than
Calculation:
Consider the formula for the hydrogen ion concentration:
Consider the hydrogen ion concentration of the well is
As the pH level is greater than
b.
To find whether the well is safe.
b.
Answer to Problem 66PPS
No, the well is not safe.
Explanation of Solution
Given:
The safe standard for arsenic level is less than
Calculation:
Consider the environmental engineer finds
And,
Therefore, the arsenic content is the well side is:
As the ppm level is greater than
c.
To find the hydrogen ion concentrationlevel that meets the troublesome pH level.
c.
Answer to Problem 66PPS
Explanation of Solution
Given:
The safe standard for arsenic level is less than
Calculation:
Consider if the hydrogen ion concentration level
Therefore the required hydrogen ion concertation level that meets the troublesome pH level is
