Black coffee has a pH around 5; hand soap has a pH of 10. How many times more acidic is coffee relative

Anon25 [30]

Answer:

$\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}$

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:

$10^ {difference \ in \ pH}$

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.

$10^5=100,000$

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>

What are photosynthesis and cellular respiration's equation and word equations?

AnnyKZ [126]

Answer: A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.
