Key formulas for pH and pOH calculations in chemistry, including the relationship between hydrogen and hydroxide ion concentrations and the sum of pH and pOH equaling 14.
A blackboard-style image displaying key formulas for pH and pOH calculations, including pH = -log[H₃O⁺], pOH = -log[OH⁻], [H₃O⁺][OH⁻] = 1 × 10⁻¹⁴, and pH + pOH = 14, with highlighted equations in blue and red boxes.
