1.) the equation for the ph of a substance is ph = –log[h+], where h+ is the concentration of hydrogen ions. what is the approximate ph of a solution if the concentration of hydrogen ions is 5.0 × 10–4 moles per liter?

a.)2.7

b.)3.0

c.)3.3

d.)3.6

c .3.3

Step-by-step explanation:

pH is the negative log of the molar hydrogen ion concentration.The equation to calculate pH is;

pH = -log10[H+]

pH = -log10(5.0 x 10-4)

pH = 3.30
