Lesson 11: Hydrolysis
Prescribed Learning Outcomes: F4, F5 Study Guide Equivalent: N1 - N4
Today you wrote a quiz involving pH and pOH calculations. After the quiz you saw that hydrolysis of a salt is a reaction between water and the cation or anion (or both) contained in the salt so as to produce an acidic or basic solution. The procedure for determining the behaviour of a salt in water is straightforward... a) determine ions produced when the salt dissociates b) discard spectator ions from further consideration c) any remaining ions will act as acids if they are on the acid side (left) of the table and/or as a base if they are on the base side (right). Here's a link to some online examples and a quiz for you to try. Want additional notes?

Lesson 7: Ion Product Constant of Water - Kw
Prescribed Learning Outcomes: E1 Study Guide Equivalent: L1 - L7
Today you handed in your lab write up for Experiment 20B. Next, you wrote a quiz on acids and bases. The lesson today showed how to write an equation to represent the ionization of water. Using the equation you were able to make predictions of how the addition of an acid or a base would affect the equilibrium system. You wrote the equilibrium expression for the ion product constant of water (Kw) and you examined how the value for Kw will change with changes in temperature. Finally you learned how to calculate the concentration of H3O+ (OH-) given the other, using Kw. Want additional notes?

Lesson 1: Introduction to Acids and Bases
Prescribed Learning Outcomes: D1, D2 Study Guide Equivalent: J2, J3, J4, J5
Today was an introduction to unit IV. The class watched a video and then you had a few minutes to brainstorm and write down everything you remember learning about acids and bases. After sharing what you wrote with a neighbour, you looked at a variety of household products and pictures, discussing how they relate to acids and bases (get PPT here) . Next, you were asked whether you agree or disagree with 3 statements. You were shown a demo using litmus and bromothymol blue indicators to test the pH of HCl, deionized water, NaOH, NaCl, Na2CO3, and NH3. You then worked in groups of three to sort unit vocabulary terms into categories. The remainder of the class was spent working on problem set #1. Want notes? Click here.
