Q1. Compare and contrast the properties of acids and bases.

Background

Topic: Properties of Acids and Bases

This question tests your understanding of the physical and chemical properties that distinguish acids from bases.

Key Terms:

• Acid: A substance that donates hydrogen ions (H+) in solution.

• Base: A substance that donates hydroxide ions (OH-) or accepts H+ in solution.

Step-by-Step Guidance

1. List common properties of acids (e.g., taste, effect on indicators, reactivity with metals).

2. List common properties of bases (e.g., taste, feel, effect on indicators).

3. Identify at least two similarities and two differences between acids and bases.

Q2. Identify the following compounds as being an acid or a base: Al(OH)3, HFO4, Ba(OH)2, HCl, HClO, Mg(OH)2, HBr

Background

Topic: Acid/Base Identification

This question tests your ability to recognize acids and bases based on their chemical formulas.

Key Concepts:

• Acids typically start with H (hydrogen) in their formula.

• Bases often contain OH (hydroxide) ions.

Step-by-Step Guidance

1. For each compound, look for the presence of H at the beginning (acid) or OH at the end (base).

2. Classify each compound accordingly.

3. Remember that some compounds may not fit the pattern perfectly—think about their behavior in water.
