  • Acid

    A substance that increases the concentration of hydrogen ions (H+) in a solution.

  • Base

    A substance that decreases the concentration of hydrogen ions (H+) in a solution.

  • What happens when hydrochloric acid (HCl) is added to water?

    It dissociates into hydrogen ions (H+) and chloride ions (Cl-), increasing the concentration of H+ ions.

  • What is the chemical formula for sodium hydroxide?

    NaOH

  • How does sodium hydroxide (NaOH) affect hydrogen ion concentration in water?
