This unit is all about acid and base chemistry. We will learn about some of the common household acids and bases and discover some of their uses in everyday life. We will investigate the pH scale and learn about indicators which determine pH levels. Equilibrium will be discussed in the context of acids and bases and Le Chatelier's Principle will be introduced. We will learn the technique of titration and make an ester in the laboratory.
TIP: When the ideal gas law applies, a mole of anygas occupies the same volume under the same conditions of temperature and pressure.
The volume that gases occupy depends on the number of moles, the gas temperature, and pressure. The volume of a particular gas changes as its temperature and/or pressure changes as shown below.
