8. the letter p in the term ph stands for the german word

potenz, which means "power" or "potential." the letter h.

represents hydrogen ions (h+). how are these related to

the definition of ph?

Here's what I get  

Explanation:

Per the above explanation, pH means "power of hydrogen ions."

The concentration of hydrogen ions is a measure of the acidity of a solution. A higher concentration represents a more acidic solution.

The definition of pH is

pH = -log[H⁺]

Thus, pH is a measure of the hydrogen ion concentration.

The more negative the pH, the greater the Potenz of hydrogen ions.
