Answer:
Explanation:
The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.
This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.
So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:
The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.
Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
