Unit 9 Honors Assignment. The terms acid and base have been defined in different ways, depending on the particular way of looking at the properties of acidity and basicity. An important limitation of the Arrhenius definitions of acids and bases is that it fails to explain how substances lacking hydroxide ions form basic solutions when dissolved in water, such as NO2 – and F–. Acidic substances are usually identified by their sour taste. The host describes strong and weak acids and bases and performs a lab demonstrating neutralization reactions and titration.

The students make ice cream to investigate colligative properties and solve problems to find the freezing point and boiling point of different substances. A base is defined as a proton acceptor (or H+ ion acceptor) by this theory. The host explains how important the concepts in this unit are to chemistry.

Online Introduction to Solutions Activity. Increases surface area so there are more places the solvent can get to the solute & less bonds for solvent to break. The batteries used to start the engines of automobiles commonly contain this acid. Acids are corrosive in nature.
