# Reverse Dilution Calculator

## Understanding Reverse Dilution in Chemical Reaction:

Reverse Dilution Calculator refers to the process of determining the original concentration of a solution before it was diluted. It allows us to work backward from diluted to concentrated solutions. This concept is particularly useful when the initial concentration of a solution is unknown, but the diluted concentration and the dilution factor are given.

## Reverse Dilution Calculator Formula:

The formula for calculating the reverse dilution factor is derived from the relationship between the final diluted concentration (Cf), the initial concentration (Ci), and the dilution (D):

**Reverse Dilution = Cf / Ci = D**

Where:

- Cf is the final diluted concentration.
- Ci is the initial concentration.
- D is the dilution.

**Example**

Suppose you have a solution with an initial concentration of 0.2 M (Ci=0.2). This solution is then diluted by a factor of 5 (D=5) to achieve a final concentration of 0.04 M (Cf=0.04). Calculate the reverse dilution factor?

Using the formula:

Reverse Dilution (D) = Cf / Ci

Initial Concentration (Ci) = Cf / D

0.004 / 5

The reverse dilution factor in this case is 0.0008

## How to Use this Calculator:

### Enter Information:

**Final Concentration:**In the “Final Concentration” input field, enter the concentration of the solution after dilution. This value should be a positive number.**Dilution Factor:**In the “Dilution Factor” input field, enter the dilution factor used to achieve the final concentration. The dilution factor is typically a decimal, like 0.1 for a 1:10 dilution.

### Click Calculate:

Click the “Calculate” button. The calculator will process the information you provided.

### View Result:

The “Original Concentration” result will appear below the “Calculate” button. This value represents the concentration of the original, undiluted solution used to create the final diluted solution.

### Reset:

If you want to perform another calculation, click the “Reset” button. This clears the input fields and results, allowing you to input new values for calculation.

## At The End

A reverse dilution calculator is a powerful tool that enables chemists to determine the original concentration of a solution before dilution. By using the relationship between initial and final concentrations, along with the dilution factor, this concept provides insights into quantitative aspects of chemical analysis and experimentation.
