Find volume to neutralize solution

In summary, volume in chemistry refers to the amount of space occupied by a substance and can be measured in units such as liters or milliliters. To calculate the volume needed to neutralize a solution, the concentration of the acid or base and the molar ratio must be known. This is important for accurately preparing solutions and understanding the strength of acids and bases. Not all acids and bases can be used to neutralize a solution, as their strength and concentration must be carefully considered. A solution is considered neutralized when it has a pH level of 7, which can be determined through pH testing or by using an indicator such as phenolphthalein.

Homework Statement


What volume in milliliters of .500 M HNO3 is required to neutralize 40.00 milliliters of a 0.200 M NaOH solution?

Homework Equations


The balanced chemical equation
HNO3(aq) + NaOH(aq) → H2O(l) + NaNO3(aq)

The Attempt at a Solution


.200 mol NaOH/1L x 0.04000 L x 1 mol HNO3/ 1 mol NaOH x 1L/ 0.500 mol HNO3 x 1 mL/(10^-3) L = 16.0 mL

I'm not sure if the procedure is correct.

A bit convoluted if you ask me (I don't like this approach to stoichiometry, not your fault), but at least it yields a correct answer.

1. What is the definition of volume in chemistry?

Volume in chemistry refers to the amount of space occupied by a substance. It is often measured in units such as liters (L) or milliliters (mL).

2. How do you calculate the volume needed to neutralize a solution?

To calculate the volume needed to neutralize a solution, you need to know the concentration (in moles) of the acid or base, as well as the molar ratio of the acid to base. The volume can be calculated using the formula: volume = (moles of acid or base) / (concentration x molar ratio).

3. Why is it important to find the volume needed to neutralize a solution?

Finding the volume needed to neutralize a solution is important because it allows us to accurately measure and prepare solutions for chemical reactions. It also helps us understand the strength and concentration of acids and bases, which is crucial for many industrial and scientific processes.

4. Can you use any acid or base to neutralize a solution?

No, not all acids and bases can be used to neutralize a solution. The strength and concentration of the acid or base must be carefully considered to ensure that the desired neutralization reaction occurs. Additionally, some acids and bases may have harmful properties and should only be handled by trained professionals.

5. How can you determine if a solution has been neutralized?

A solution is considered neutralized when it has a pH level of 7, which is neither acidic nor basic. This can be determined using pH test strips or a pH meter. Another way to tell if a solution has been neutralized is by adding an indicator, such as phenolphthalein, which changes color when the solution reaches a neutral pH level.
