📚 Part 1: Understanding Salt Hydrolysis

1. What is salt hydrolysis?

The dissolving of salt in water

The reaction of salt ions with water to produce H⁺ or OH⁻ ions

The formation of crystals when salt is heated

The breaking down of salt into its elements

2. When sodium acetate is dissolved in water, what happens to the pH?

pH decreases (becomes acidic)

pH increases (becomes basic)

pH remains neutral

pH cannot be determined

3. Which of the following determines whether a salt solution will be acidic, basic, or neutral? (Check all that apply)

The strength of the parent acid

The strength of the parent base

The temperature of the water

The colour of the salt

4. Complete the definition: Salt hydrolysis is the reaction of _______ ions with _______ to produce either _______ or _______ ions.

Salt hydrolysis is the reaction of _______ ions with _______ to produce either _______ or _______ ions.

5. Predict whether each salt solution will be acidic, basic, or neutral when dissolved in water:

a) Sodium chloride (NaCl): _____________

b) Ammonium chloride (NH₄Cl): _____________

c) Sodium carbonate (Na₂CO₃): _____________

6. Explain why some salts taste sour while others feel slippery when dissolved in water.

7. Give one example of an everyday salt and predict whether its aqueous solution would be acidic, basic, or neutral. Explain your reasoning.

8. Why is understanding salt hydrolysis important in real-life applications?
