LARUTAN KLORIN, Cara Membuat: Tutorial

Introduction

This tutorial explains how to create a 1% chlorine solution from a concentrated 15% chlorine solution. Chlorine solutions are widely used for disinfecting drinking water and wastewater. Understanding how to prepare these solutions safely and accurately is essential for effective water treatment.

Step 1: Calculate the Amount of Concentrated Chlorine Needed

To create a 1% chlorine solution from a 15% chlorine solution, you need to determine how much of the concentrated solution is required for 1,000 liters of the dilute solution.

1. Determine the volume of chlorine needed:
   • Use the formula: [ \text{Volume of concentrated chlorine} = \left( \frac{\text{Desired concentration}}{\text{Concentration of stock solution}} \right) \times \text{Total volume of diluted solution} ]
   • For a 1% solution from a 15% stock solution: [ \text{Volume of concentrated chlorine} = \left( \frac{1}{15} \right) \times 1000 \text{ liters} = 66.67 \text{ liters} ]

Step 2: Measure the Water

You will need to measure the amount of clean water required to dilute the concentrated chlorine solution.

1. Calculate the total volume of water:
   • Subtract the volume of concentrated chlorine from the total desired volume: [ \text{Volume of water} = \text{Total volume} - \text{Volume of concentrated chlorine} ]
   • For 1,000 liters: [ \text{Volume of water} = 1000 \text{ liters} - 66.67 \text{ liters} = 933.33 \text{ liters} ]

Step 3: Prepare the Solution

Now that you have the required volumes, you can prepare the chlorine solution.

1. Gather your materials:

   • 66.67 liters of 15% concentrated chlorine
   • 933.33 liters of clean water
   • A large mixing tank (capable of holding at least 1,000 liters)
   • Protective gear (gloves, goggles)

2. Add the concentrated chlorine to the tank:

   • Carefully pour the 66.67 liters of concentrated chlorine into the mixing tank.

3. Add clean water:

   • Gradually add the 933.33 liters of clean water to the tank, ensuring proper mixing.

4. Mix thoroughly:

   • Stir the solution well to ensure that the concentrated chlorine is evenly distributed throughout the water.

Step 4: Safety Precautions

When handling chlorine solutions, safety is paramount.

1. Wear protective gear:

   • Always use gloves and goggles to protect your skin and eyes from chlorine exposure.

2. Ensure proper ventilation:

   • Work in a well-ventilated area to avoid inhaling any fumes.

3. Store the solution safely:

   • Keep the prepared chlorine solution in a secure container away from children and pets.

Conclusion

In this tutorial, you learned how to prepare a 1% chlorine solution for disinfecting water. The key steps included calculating the required volumes of concentrated chlorine and clean water, preparing the solution, and observing safety precautions. By following these steps, you can effectively create a chlorine solution suitable for water disinfection.
