Question

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?

Answer 2

Answer:

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
