You will get to go through laboratory simulations, explore the basic properties of acids and bases and learn how to name them as well as identify acid-base reactions.
After completing this tutorial, you will be able to complete the following:
How did Swiss chemist Svante Arrhenius explain the difference between acids and bases?
~ Arrhenius stated that acids produce hydrogen ions when dissolved in water and bases produce hydroxide ions when dissolved in water.
According to the Bronsted-Lowry definition of acids and bases, acids are substances that donate protons and bases are substances that accept protons. What fault do scientists find with this definition?
~ The Bronsted-Lowry definition of acids and bases is broader than the Arrhenius definition. However, the Bronsted-Lowry definition still fails to explain the properties of acids or bases that do not contain hydrogen.
How did American chemist Gilbert Lewis define acids and bases?
~ According to Lewis's definition, acids are substances that accept electrons and bases are substances that donate electrons. This definition can be used to classify all substances, regardless of whether they contain hydrogen.
Based on the Lewis definition of acids and bases, what will occur if an acid is introduced to a base?
~ Lewis stated that the acidic and basic properties of substances are related to electron transfer. Based on the Lewis definition, if an acid is introduced to a base, the acid will accept an electron pair from the base, and the base will donate an electron pair to the acid.
