Chapter 8: Problem 58

Write (a) a reaction with all species intact and using \((a q),(s)\), or \((l)\) for the reaction between aqueous solutions of sulfuric acid and calcium hydroxide. (b) What salt is formed as a result of neutralization?

Short Answer

Expert verified
a) The balanced chemical equation for the reaction between aqueous solutions of sulfuric acid and calcium hydroxide is: \( H_{2}SO_{4}(aq) + Ca(OH)_{2}(aq) \rightarrow 2H_{2}O(l) + CaSO_{4}(aq) \) b) The salt formed as a result of the neutralization is calcium sulfate (CaSO₄).

Step by step solution

01

Write the formulas for the reactants.

The reactants are sulfuric acid (H₂SO₄) and calcium hydroxide (Ca(OH)₂). Both are in aqueous solution, so their formulas are followed by the symbol (aq).
02

Write the formulas for the products.

In a neutralization reaction between an acid and a base, the products are water (H₂O) and a salt. The salt formed in this reaction consists of the cation of the base (Ca²⁺) and the anion of the acid (SO₄²⁻). The formula for the salt is calcium sulfate (CaSO₄). Since the reactants are in aqueous solution, the products will also be in aqueous solution, so we will use the symbol (aq) for the salt. Water is a liquid, so it is followed by the symbol (l).
03

Combine reactants and products.

Now we have the reactants and the products, so we can write the unbalanced chemical equation: H₂SO₄(aq) + Ca(OH)₂(aq) → H₂O(l) + CaSO₄(aq)
04

Balance the chemical equation.

Let's balance the chemical equation. The sulfur and calcium atoms are already balanced, but we need to balance the hydrogen and oxygen atoms. We can do this by multiplying the water molecule by 2: H₂SO₄(aq) + Ca(OH)₂(aq) → 2 H₂O(l) + CaSO₄(aq) Now, the chemical equation is balanced. a) The balanced chemical equation for the reaction between aqueous solutions of sulfuric acid and calcium hydroxide is: H₂SO₄(aq) + Ca(OH)₂(aq) → 2 H₂O(l) + CaSO₄(aq) b) The salt formed as a result of the neutralization is calcium sulfate (CaSO₄).

Most popular questions from this chapter

Write the balanced equation, the complete ionic equation, and the net ionic equation for the neutralization reaction that occurs when nitric acid, \(\mathrm{HNO}_{3}\), is mixed with calcium hydroxide, \(\mathrm{Ca}(\mathrm{OH})_{2}\)

Carbon dioxide gas and calcium oxide are produced when calcium carbonate, \(\mathrm{CaCO}_{3}\), is heated strongly. Write the balanced equation for this process.

(a) True or false? It is possible for a reaction to be simultaneously a single-replacement reaction and a combination reaction. (b) True or false? It is possible for a reaction to be simultaneously a double-replacement reaction and a neutralization reaction. If either statement is false, explain why.

What does it mean when the label (aq) is attached to the formula for an ionic compound?

Balance this equation and classify it as combination, decomposition, single- replacement, or double-replacement: \(\mathrm{K}_{2} \mathrm{CrO}_{4}+\mathrm{Al}\left(\mathrm{NO}_{3}\right)_{3} \rightarrow \mathrm{Al}_{2}\left(\mathrm{CrO}_{4}\right)_{3}+\mathrm{KNO}_{3}\)
