Question

Acidity is measured on the pH scale. The acidity of a substance is given by pH = -log H, where H is the concentration of Hydrogen ions.
If a substance has an H value of 0.00032, which shows a valid step in the process of calculating the pH of the substance?
Select the correct answer below:
pH = -log 0.0032
-log(3.2 10 4) = pH
log(3.2 10 ) = pH
log (3.2 10) = -pH
pH = log 0.00032
