Introduction

In the world of chemistry, balancing chemical equations is a crucial skill that every chemist must possess. It not only helps in understanding the stoichiometry of a reaction but also aids in predicting the amount of reactants and products formed. In this article, we will delve into a classic problem that involves the neutralization reaction between sulfuric acid (H2SO4) and sodium hydroxide (NaOH). We will explore the balanced chemical equation, calculate the number of moles of H2SO4 used, and determine the concentration of the NaOH solution.

The Balanced Chemical Equation

The balanced chemical equation for the neutralization reaction between H2SO4 and NaOH is given as:

2 NaOH+H2SO4→Na2SO4+2 H2O{ 2 \, \text{NaOH} + \text{H}_2\text{SO}_4 \rightarrow \text{Na}_2\text{SO}_4 + 2 \, \text{H}_2\text{O} }

This equation shows that 2 moles of NaOH react with 1 mole of H2SO4 to produce 1 mole of Na2SO4 and 2 moles of H2O.

Calculating the Number of Moles of H2SO4 Used

The chemist uses 0.25 L of 2.00 M H2SO4 to completely neutralize 2.00 L of NaOH solution. To calculate the number of moles of H2SO4 used, we can use the formula:

Number of moles=Molarity×Volume (in L){ \text{Number of moles} = \text{Molarity} \times \text{Volume (in L)} }

Substituting the given values, we get:

Number of moles of H2SO4=2.00 M×0.25 L=0.50 mol{ \text{Number of moles of H}_2\text{SO}_4 = 2.00 \, \text{M} \times 0.25 \, \text{L} = 0.50 \, \text{mol} }

Determining the Concentration of the NaOH Solution

Since the balanced chemical equation shows that 2 moles of NaOH react with 1 mole of H2SO4, we can calculate the number of moles of NaOH required to react with 0.50 mol of H2SO4:

Number of moles of NaOH=2×Number of moles of H2SO4=2×0.50 mol=1.00 mol{ \text{Number of moles of NaOH} = 2 \times \text{Number of moles of H}_2\text{SO}_4 = 2 \times 0.50 \, \text{mol} = 1.00 \, \text{mol} }

Now, we can calculate the concentration of the NaOH solution using the formula:

Concentration=Number of molesVolume (in L){ \text{Concentration} = \frac{\text{Number of moles}}{\text{Volume (in L)}} }

Substituting the values, we get:

Concentration of NaOH=1.00 mol2.00 L=0.50 M{ \text{Concentration of NaOH} = \frac{1.00 \, \text{mol}}{2.00 \, \text{L}} = 0.50 \, \text{M} }

Conclusion

In this article, we have explored the balanced chemical equation for the neutralization reaction between H2SO4 and NaOH. We have calculated the number of moles of H2SO4 used and determined the concentration of the NaOH solution. This problem demonstrates the importance of balancing chemical equations and understanding stoichiometry in chemistry.
