Answer:
pOH = 9.
Explanation:
The inverse relationship between the pH and pOH of any given solution can be written as:
pH = 14 - pOH
Or conversely:
pOH = 14 - pH
With the above information in mind we can <u>use the given pH to calculate the pOH</u>:
pOH = 14 - pH
pOH = 14 - 5
pOH = 9
Thus, black coffee has a pOH of 9.

Answer:
Sulfur (Acidic)
Explanation:
Lime would just add to the amount of alkalinity, and water would do nothing much due to it being neutral.
Sulfur, which is acidic, will neutralize the pH level. The opposite of Alkalinity is Acidity, and Neutrality is in the middle of the two.
