Base (química)

The video explains the nature of bases, which are typically metal oxides, hydroxides, or carbonates. In chemical reactions, bases interact with hydrogen ions and produce hydroxide ions in solutions. While most bases are insoluble in water, those that dissolve form alkaline solutions with a pH greater than 7.

Which of the following is typically considered a base?

• Acid

• Salt
