## Calculate the Concentration of Nitric Acid

Nitric acid is a highly corrosive and toxic acid used in a variety of industrial and laboratory applications. It is essential to know the concentration of nitric acid in any given solution to ensure the safety and effectiveness of its use. In this article, we will discuss how to calculate the concentration of nitric acid.

Concentration of Nitric Acid:

The concentration of nitric acid is typically expressed in molarity (M), which is defined as the number of moles of nitric acid per liter of solution. To calculate the concentration of nitric acid, we need to know the number of moles of nitric acid and the volume of the solution.

The formula to calculate the concentration of nitric acid is:

Concentration of Nitric Acid (M) = Number of Moles of Nitric Acid / Volume of Solution (L)

To determine the number of moles of nitric acid in a solution, we can use the following formula:

Number of Moles of Nitric Acid = Mass of Nitric Acid (g) / Molar Mass of Nitric Acid (g/mol)

The molar mass of nitric acid is 63.01 g/mol.

Example Calculation:

Suppose we have 250 mL of a solution containing 4.5 g of nitric acid. What is the concentration of nitric acid in the solution?

First, we need to convert the volume to liters:

250 mL = 0.25 L

Next, we can calculate the number of moles of nitric acid:

Number of Moles of Nitric Acid = 4.5 g / 63.01 g/mol = 0.071 mol

Finally, we can calculate the concentration of nitric acid:

Concentration of Nitric Acid = 0.071 mol / 0.25 L = 0.284 M

Therefore, the concentration of nitric acid in the solution is 0.284 M.

Conclusion:

Calculating the concentration of nitric acid is crucial for ensuring the safety and effectiveness of its use in various applications.

By using the formula to calculate the concentration of nitric acid, we can determine the number of moles of nitric acid in a given solution and express the concentration in molarity. It is essential to handle nitric acid with care and follow proper safety protocols.

FAQs on ‘Calculate the Concentration of Nitric Acid’:

Q: What is nitric acid? A: Nitric acid is a highly corrosive and toxic chemical compound with the formula HNO3. It is commonly used in the production of fertilizers, dyes, and explosives.

Q: Why is it important to calculate the concentration of nitric acid? A: Knowing the concentration of nitric acid is important for many industrial processes and laboratory experiments. It can also help ensure the safety of workers handling the acid, as higher concentrations can be more hazardous.
