Understanding pH Calculations

What is the formula to calculate pH from hydronium ion concentration?

• pH = log(H+)

• pH = -log(H+)

• pH = H+ * 10

• pH = 10^(H+)

If the hydronium ion concentration is 1 * 10^-4 M, what is the pH of the solution?

• 3

• 2

• 4

• 5

How do you calculate the hydronium ion concentration from a given pH?

• H+ = log(pH)

• H+ = 10^(-pH)

• H+ = -log(pH)

• H+ = pH * 10

What is the pH of a solution with a hydroxide ion concentration of 0.36 M?

• 10.6

• 12.6

• 13.6

• 11.6

What is the relationship between pH and pOH in a solution?

• pH + pOH = 10

• pH + pOH = 0

• pH + pOH = 7

• pH + pOH = 14
