# Concentration of a salt produced by neutralization reaction

• Javeria
In summary: This means that the final volume is essentially just the sum of the initial volumes, as the small differences in volume are negligible. In summary, the conversation is about a neutralization reaction between sulfuric acid and sodium hydroxide. The correct answer is A, which is the concentration of sodium sulfate produced by the reaction. The volume of sodium sulfate is not given, but it can be assumed to be the sum of the initial volumes of sulfuric acid and sodium hydroxide as the small differences in volume produced by the reaction are negligible. The neutralization reaction results in the production of water and some ions disappearing, but their volumes are similar to the initial volumes of the reacting ions.

## Homework Statement

10.00 cm3 of 1.00 mol dm–3 sulfuric acid is fully neutralized by 20.00 cm3 of 1.00 mol dm–3 of sodium hydroxide. What is the concentration, in mol dm–3, of sodium sulfate solution produced by the reaction?
A 0.33
B 0.50
C 0.67
D 1.00

## Homework Equations

Mol = Concentration * Volume (dm^3)

## The Attempt at a Solution

I calculated the number of moles of sodium sulfate which are 0.01 mol from the formula and ratio between the moles of sulfuric acid:sodium sulfate or sodium hydroxide:sodium sulfate. We don't have the volume of sodium sulfate. If i take the volume as 30 cm^3 for sodium sulfate then i get the correct answer A but water is present too so that's not possible, please explain!

Yes, there are minute amounts of water produced, but also some of the ions that were present disappeared. These effects mostly cancel out so you can safely assume the final volume is just sum of volumes.

Oh okay, how do the ions disappear?

What is the neutralization reaction?

H+1 and OH-1 form water and the other ions are spectator ions so they cancel out. OH OKAY. But then if they're disappearing why do they have a volume?

It is not like they are disappearing out of this world - write the reaction equation. Two ions disappear, something appears. Volumes of the reacting ions and the product are not exactly identical, but they are quite similar.

## What is meant by concentration of a salt produced by neutralization reaction?

The concentration of a salt produced by neutralization reaction refers to the amount of the salt present in a solution, typically measured in moles per liter (M). It is a measure of how much of the salt is dissolved in the solution, and is influenced by factors such as the amount of acid and base used in the neutralization reaction and the volume of the resulting solution.

## How is the concentration of a salt produced by neutralization reaction calculated?

The concentration of a salt produced by neutralization reaction can be calculated using the formula: concentration (M) = moles of salt / volume of solution (L). This requires knowing the number of moles of the salt produced in the reaction, which can be determined from the balanced chemical equation and the amount of acid and base used.

## What is the relationship between the concentration of a salt produced by neutralization reaction and the strength of the acid and base used?

The concentration of a salt produced by neutralization reaction is directly influenced by the strength of the acid and base used. Stronger acids and bases will result in a higher concentration of salt in the solution, while weaker acids and bases will result in a lower concentration of salt.

## How does temperature affect the concentration of a salt produced by neutralization reaction?

Temperature can impact the concentration of a salt produced by neutralization reaction in a few ways. Higher temperatures can increase the rate of the reaction, resulting in a higher concentration of salt in a shorter amount of time. Additionally, some salts may have different solubility levels at different temperatures, which can affect their concentration in a solution.

## What are some practical applications of understanding the concentration of a salt produced by neutralization reaction?

Understanding the concentration of a salt produced by neutralization reaction is important in various industries and fields, such as chemistry, medicine, and environmental science. It can be used to determine the effectiveness of a neutralization reaction, to monitor the progress of a reaction, and to ensure the proper concentration of a solution for specific applications. Additionally, knowledge of the concentration of a salt can help in the production of specific salts for various purposes, such as in food and pharmaceuticals.
