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 10⁵ or 100,000 times more acidic than hand soap.

With what kinds of bacteria did Griffith inject mice

Aneli [31]

The S strain of bacteria that Griffith used was virulent meaning that when injected into the mouse, the mouse would die from pneumonia The R strain was nonvirulent and did not result in the death of the mouse. When Griffith injected mice with a dead S strain of pneumatic bacteria the mice remained healthy.

I hope this helps!
