Question

COPY out the following sentences and fill in the gaps.

1. Sulfuric acid releases _____________ ions in solution. This makes the solution _______________________.

2. Sodium hydroxide is an ___________________. It releases ____________________ ions in solution. This makes the solution __________________________.

3. Write word and symbol equations for both of the above situations, a template is given below.

Sulfuric acid --> _____________ + ___________________

________ --> ___________ + ______________

Sodium hydroxide --> _____________________ + ___________________

______________ --> ______________ + __________________

Answer 1

1. Hydrogen ions; acidic

2. Alkali; hydroxide ions; alkaline

3a. Sulfuric acid --> 2 Hydrogen ions + sulfate ion

H₂SO₄ --> 2H+ + SO₄²-

3b. Sodium hydroxide --> Sodium ion + Hydroxide ion

NaOH --> Na+ + OH-

Step-by-step explanation:

1. Sulfuric acid releases hydrogen ions in solution. This makes the solution acidic.

Acids produce hydrogen ions when dissolved in aqueous solutions.

2. Sodium hydroxide is an alkali. It releases hydroxide ions in solution. This makes the solution alkaline.

Alkalis are soluble bases that produce hydroxide ions in solution.

3a. Sulfuric acid --> 2 Hydrogen ions + sulfate ions

H₂SO₄ --> 2H+ + SO₄²-

The equation above is for the ionization of sulfuric acid

b. Sodium hydroxide --> Sodium ion + Hydroxide ion

NaOH --> Na+ + OH-

The equation above is for the ionization of sodium hydroxide
