Introduction

In this article, we will explore the reaction between nitric acid (HNO3) and sodium hydroxide (NaOH) and calculate the volume of sodium hydroxide required to completely react with a given sample of nitric acid. The reaction between nitric acid and sodium hydroxide is a classic example of a neutralization reaction, where the acid (HNO3) reacts with the base (NaOH) to form a salt (NaNO3) and water (H2O).

The Reaction Between Nitric Acid and Sodium Hydroxide

The reaction between nitric acid and sodium hydroxide can be represented by the following equation:

${ \text{HNO}_3(aq) + \text{NaOH}(aq) \rightarrow \text{NaNO}_3(aq) + \text{H}_2\text{O}(l) }$

In this equation, the nitric acid (HNO3) reacts with the sodium hydroxide (NaOH) to form sodium nitrate (NaNO3) and water (H2O). This reaction is a classic example of a neutralization reaction, where the acid (HNO3) donates a proton (H+), and the base (NaOH) accepts the proton, resulting in the formation of a salt (NaNO3) and water (H2O).

Calculating the Number of Moles of Nitric Acid

To calculate the volume of sodium hydroxide required to completely react with the given sample of nitric acid, we first need to calculate the number of moles of nitric acid present in the sample. The number of moles of nitric acid can be calculated using the formula:

${ \text{Number of moles} = \text{Molarity} \times \text{Volume (in liters)} }$

In this case, the molarity of the nitric acid is 0.100 M, and the volume of the sample is 25 mL, which is equivalent to 0.025 L. Therefore, the number of moles of nitric acid can be calculated as follows:

${ \text{Number of moles} = 0.100 \, \text{M} \times 0.025 \, \text{L} = 0.0025 \, \text{mol} }$

Calculating the Number of Moles of Sodium Hydroxide Required

Since the reaction between nitric acid and sodium hydroxide is a 1:1 reaction, the number of moles of sodium hydroxide required to completely react with the given sample of nitric acid is equal to the number of moles of nitric acid present in the sample. Therefore, the number of moles of sodium hydroxide required is also 0.0025 mol.

Calculating the Volume of Sodium Hydroxide Required

To calculate the volume of sodium hydroxide required to completely react with the given sample of nitric acid, we need to divide the number of moles of sodium hydroxide required by the molarity of the sodium hydroxide. The molarity of the sodium hydroxide is 0.0500 M. Therefore, the volume of sodium hydroxide required can be calculated as follows:

${ \text{Volume} = \frac{\text{Number of moles}}{\text{Molarity}} = \frac{0.0025 \, \text{mol}}{0.0500 \, \text{M}} = 0.05 \, \text{L} }$

Since the volume of the sodium hydroxide required is 0.05 L, which is equivalent to 50 mL, we can conclude that the volume of sodium hydroxide required to completely react with the given sample of nitric acid is 50 mL.

Conclusion

In this article, we explored the reaction between nitric acid (HNO3) and sodium hydroxide (NaOH) and calculated the volume of sodium hydroxide required to completely react with a given sample of nitric acid. The reaction between nitric acid and sodium hydroxide is a classic example of a neutralization reaction, where the acid (HNO3) reacts with the base (NaOH) to form a salt (NaNO3) and water (H2O). We calculated the number of moles of nitric acid present in the sample and used this value to calculate the number of moles of sodium hydroxide required to completely react with the given sample of nitric acid. Finally, we calculated the volume of sodium hydroxide required to completely react with the given sample of nitric acid and found that it is 50 mL.
