DISCUSSION 1:

Think of common household substances (food, drink, cleaning supplies etc.) that we use at home that are either acidic or basic. List at least 5 and identify the type of acids or bases present in them. Would you categorize each of the item you listed as weak or strong acids or bases?

DISCUSSION 2:

Antacids are sometimes recommended to take to relieve heartburn, indigestion (due to excess acid);

• Which acid is present in our stomach?
• Would you categorize it as a strong or weak acid?
• What type of chemical reaction take place to help remove the excess acid in the stomach whenever antacids are used?
• Write the NET ionic equation of the reaction between an antacid and stomach acid. (Table 4.4 lists the common antacids).

DISCUSSION 3:

Distinguish between strong and weak electrolytes in terms of the arrows in the reaction: which one do we use single arrow in one direction for and which one do we use half-arrows (double-arrows) in both directions for? Explain your reason(s) in details using relevant chemical equations as examples.

DISCUSSION 4:

a. Discuss the main product in precipitation reactions.

b. Why do we need to write net reactions in the reactions described in chapter 4 (Precipitation, Oxidation-reduction, Neutralization reactions) after writing the molecular and complete ionic reactions? Use chemical equations as examples.

DISCUSSION 5:

Discuss two applications of Oxidation-Reduction (REDOX) reaction in real life. Use relevant chemical equations/reactions to support the applications.
