Chapter 11.4, Problem 28PP
Interpretation Introduction

Interpretation:

If 14.0g of Al(OH)3 is present in an antacid tablet, the theoretical yield of AlCl3 produced needs to be determined when the tablet reacts with HCl.

Concept introduction:

An actual yield is the mass of a product actually obtained from the reaction. It is usually less than the theoretical yield.

Answer to Problem 28PP

Theoretical yield of AlCl3 is 23.9g.

Explanation of Solution

Given: Aluminium hydroxide is often present in antacids to neutralize the stomach acid (HCl). The reaction occurs as follow:

Al(OH)3(s)+3HCl(aq)AlCl3(aq)+3H2O(l)

Step 1: Balance the chemical equation:

Al(OH)3(s)+3HCl(aq)AlCl3(aq)+3H2O(l)

Step 2: Make mass to mole fraction.

For conversion from mass to moles, we divide mass by molecular mass, so in this case moles of Al(OH)3 is:

14g of Al(OH)3×1 mole Al(OH)378.0 g Al(OH)3=0.179 mole Al(OH)3

Step 3: Make mole to mole conversion

We know from balanced chemical equation that 1 mole Al(OH)3 produces 1 mole of AlCl3, therefore moles of AlCl3 produced by 0.179 mole of Al(OH)3 is:

0.179 mole Al(OH)3×1 mole AlCl31.0 mole Al(OH)3=0.179 mole AlCl3

Step 4: Make mole to mass conversion:

From conversion from moles to mass, we multiply moles by molecular mass, so in this case mass of AlCl3 is:

0.179 mole AlCl3×133.3g of AlCl3=23.9g

Conclusion

Theoretical yield of AlCl3 is 23.9g.
