Question

Acidity is measured on the pH scale. The acidity of a substance is given by pH=−logH, where H is the concentration of Hydrogen ions. If a substance has an H value of 0.0008, what is the pH of the substance, rounded to the nearest tenth?

Answer 1

Answer:

  3.1

Step-by-step explanation:

Put the concentration value in the formula and evaluate.

  pH = -log(0.0008) = -(-3.09691) = 3.09691

  pH ≈ 3.1
