What is the difference between a monoprotic acid and a diprotic acid?

A monoprotic acid can donate only one proton (+) per molecule, such as HCl. A diprotic acid can donate two protons per molecule, such as H₂SO₄.

Define the term “ionization constant” (Ka) for acids.

The ionization constant (Ka) is the equilibrium constant for the dissociation of a weak acid in water. It measures the strength of an acid. A higher Ka value indicates a stronger acid.

What is the role of indicators in acid-base titrations?

Indicators are substances that change color to signal the endpoint of an acid-base titration. They help to visually indicate when the acid has been completely neutralized by the base (or vice versa).   Related Questions: Define and give examples of Arrhenius acids?
