Question

What relationship do you find between the pH number and the power of 10 used to express the [H+]? pH = exponent of concentration values pH = reciprocal of the H+ concentration pH = the negative of the exponent of concentration pH = the H+ concentration

Answer 1

Answer: Option (c) is the correct answer.

Step-by-step explanation:

When acidity or alkanity of water soluble substances is measured then it is known as pH.

Mathematically, pH =
`-log [H^(+)]`

where
`H^(+)` = concentration of hydrogen ions.

Therefore, we can conclude that out of the given options, relationship between the pH number and the power of 10 used to express the [H+] is that pH = the negative of the exponent of concentration.

Answer 2

I think the correct answer would be the third option. The relationship you would find between the pH number and the power of 10 that is used to express the [H+] would be pH = the negative of the exponent of concentration pH. The value of pH is used as a measure of acidity of a solution and is related to the [H+] concentration.
