Chemistry 3, Task 2, Sec. 13.2 Acid Strength
Pages 529 - 534
Due on Thursday, Apr. 23, 2020
By the end of this section, you will be able to:
Compare strong and weak acids.
Establish the relation between the strength of an acid and its conjugate base.
Write the water ionization constant to predict if a solution is acidic, basic or neutral.
Watch the attached video recording titled “Comparison of Strong and Weak Acids” to differentiate between different aspects of acids and their conjugate bases.
Question 1
1.
How do you describe the strength of the conjugate bases of strong and weak acids?
Question 2
2.
When do you say that an acid is an oxyacid?
Question 3
3.
Name two commonly known strong acids and two commonly know weak acids.
Question 4
4.
Write the acid dissociation constant Ka of sulfuric acid (H2SO4) when it completely dissociates in water.
Watch the attached video recording titled “Sample Exercise: Comparison of Strong and Weak Acids and their Conjugate Bases” to understand how we solve exercises related to the arrangement of acids and conjugate bases according to their strength.
Question 5
5.
Use table 13-2 below to arrange the following monoprotic acids in increasing order of their acidity. The acids are: Chlorous acid, water, Phenol, Acetic acid.
Question 6
6.
Arrange the following acids Chlorous acid, water, Phenol, Acetic acid in
decreasing strength of their conjugate bases.
Watch the attached video recording titled “Ionization Constant of Water” to understand how to predict the type or nature of a solution using the ionization constant of water.
