Step-by-step explanation:
Invert and multiply the second fraction.

All 4 parts of the two fractions can be factored into simpler factors.

Numerous cancelations can occur
- (x - 5) [top right with x - 5 bottom left]
- (x - 2) [top left with x - 2 bottom right]
Answer
ok. We are given the following equation:

Where:

Since we are asked to determine "H" we will solve for "H" in the equation. To do that we will first multiply both sides by -1:

Now, we will use the following property of logarithms:

Applying the property and having into account that:

We get:

Now we substitute the given value of "pH = 4.5":

Solving the operation:

Therefore, the hydrogen ion concentration of the fluid is 0.000032
