Calculating the titration of acids and bases

Assumes a strong monoprotic acid and a strong monohydroxide base in water at 25 °C, additive volumes and Kw = 10⁻¹⁴. Weak acids and bases need additional equilibrium constants. OpenStax

📝 Information

pH: A measure of the acidity or basicity of a solution.

Formula: pH = -log[H⁺]

Range: From 0 to 14

pH < 7: Acidic (Red)

pH = 7: Neutral (Green)

pH > 7: Basal (Blue)

Relationship: pH + pOH = 14
