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

Option (c) is the correct answer.

Explanation:

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

Mathematically,        pH =

where             = 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.
