Which Of The Following Best Represents The Reaction Between Sulfuric Acid And Calcium Hydroxide?

Sulfuric acid (H2SO4) is a strong acid, while calcium hydroxide (Ca(OH)2) serves as its strong base. When these two substances combine, a double displacement reaction occurs; in this reaction, the positive and negative ions from both reactants exchange places to form new compounds.

The reaction between sulfuric acid and calcium hydroxide can be represented by the following equation:

H2SO4 + Ca(OH)2 = CaSO4 + 2H2O.

In this equation, H2SO4 represents sulfuric acid, Ca(OH)2 signifies calcium hydroxide, CaSO4 signifies calcium sulfate, and H2O signifies water.

When sulfuric acid is added to calcium hydroxide, hydrogen ions (H+) from the acid combine with hydroxide ions (OH-) from the base to form water (H2O). This initial step can be represented as follows:

H2SO4 + 2OH = SO42- + 2H2O.

Next, the sulfate ion (SO42-) from the acid reacts with the calcium ion (Ca2+) from the base to form calcium sulfate (CaSO4) – a white solid that precipitates out of the solution. This is known as step two of the reaction and can be represented as follows:

Ca2+ + SO42- -> CaSO4.

How to Balance:

Ca(OH)2 + H2SO4 – CaSO4 + H2O

Word Equation: Calcium hydroxide + Sulfuric acid – Calcium sulfate + Water

Chemical Reaction Type: For this chemical reaction, we have a neutralization reaction.

Balancing Strategies: In this reaction, calcium hydroxide and sulfuric acid come together in a neutralization reaction.

Be sure to count all hydrogen atoms on the reactant side of the equation. When balancing chemical equations, we should aim for each type of atom in equal numbers on both sides.

What is Sulfuric Acid?

Sulfuric acid, also known as oil of vitriol, is a highly corrosive and dense liquid with the chemical formula H2SO4. It finds widespread application in chemical industries for producing fertilizers, detergents, and dyes; additionally, it’s employed as a strong acid in batteries for pH control in various industrial processes and explosive production.

What Is Calcium Hydroxide?

Calcium hydroxide, slaked lime, or calcium hydroxide, is a white crystalline solid with the chemical formula Ca(OH)2. It’s produced by adding water to calcium oxide (commonly referred to as quicklime). Calcium hydroxide finds widespread application in construction projects both as a cement additive and for wastewater treatment.

Sulfuric Acid and Calcium Hydroxide in Reaction

Sulfuric acid and calcium hydroxide undergo a double displacement reaction, commonly called an acid-base reaction. This chemical equation describes this reaction:

H2SO4 + Ca(OH)2 = CaSO4 + 2H2O.

In this reaction, sulfuric acid (H2SO4) reacts with calcium hydroxide (Ca(OH)2) to form calcium sulfate (CaSO4) and water (H2O). Calcium sulfate is an insoluble white solid that precipitates out of the solution, leaving behind a clear and colorless water solution.

Mechanism of Reaction

Sulfuric acid and calcium hydroxide undergo a two-step reaction. In the initial stage, sulfuric acid dissociates into hydrogen ions (H+) and sulfate ions (SO42-).

H2SO4 – 2H+ + SO42-

In the second step, calcium hydroxide dissociates into calcium ions (Ca2+) and hydroxide ions (OH-):

Ca(OH)2 – Ca2+ + 2OH-

As the hydrogen ions from sulfuric acid react with hydroxide ions from calcium hydroxide, they combine to form water:

2H+ + 2OH- – 2H2O

In this equation, sulfuric acid (H2SO4) reacts with calcium hydroxide (Ca(OH)2) to form calcium sulfate (CaSO4) and water (H2O). This reaction is exothermic, meaning it releases heat energy.

Understanding the Reaction Mechanism

The reaction between sulfuric acid and calcium hydroxide takes place in several steps, as follows:

Step 1: Formation of Sulfuric Acid

In the initial step, sulfuric acid acts as a Bronsted-Lowry acid and donates a proton (H+) to an OH- ion from calcium hydroxide, creating bisulfate ion (HSO4-) and water.

Step 2: Formulation of Calcium Sulfate

Schritt 1: Combine H2SO4 with anhydrous ammonia solution and then add H2O.

In the second step, bisulfate reacts with another hydroxide ion to form water and sulfate (SO42-) ion (Ca2+). Finally, calcium ions from calcium hydroxide combine with this sulfate ion to form calcium sulfate.

Step 3: Neutralization of Remaining Acid

In the final step, any remaining acid is neutralized by the hydroxide ions from calcium hydroxide to form water.

H+ + OH- – H2O

In conclusion, the reaction mechanism between sulfuric acid and calcium hydroxide can be summarized as follows:

H2SO4 + Ca(OH)2 = CaSO4 + 2H2O.
