How do I make 500ml of a 0.3% chlorine dioxide solution from 6.4% tablets?
To make a 500ml solution of 0.3% chlorine dioxide, you'll need to dilute the concentrated tablets. Here's how you can calculate the quantities you need:
Step 1: Understand the problem
You have a 6.4% chlorine dioxide solution in tablet form, and you want to make a 0.3% solution of chlorine dioxide with a total volume of 500ml.
Step 2: Determine the initial concentration
The tablets have a concentration of 6.4%. This means that for every 100ml of solution, there is 6.4g of chlorine dioxide.
Step 3: Calculate the amount of chlorine dioxide needed
To calculate the amount of chlorine dioxide needed for a 0.3% solution, we can use the formula:
(Desired concentration / Initial concentration) × Desired volume
Plugging in the values, we get:
(0.3 / 6.4) × 500ml = 23.4375ml
So, you'll need 23.4375ml of the 6.4% concentrate.
Step 4: Calculate the amount of diluent needed
To determine the amount of diluent needed, subtract the volume of the concentrate from the desired total volume:
500ml - 23.4375ml = 476.5625ml
So, you'll need 476.5625ml of a diluent, such as water, to make up the total volume.
Step 5: Dilution process
Take the calculated amount (23.4375ml) of the 6.4% chlorine dioxide solution and add it to the predetermined amount (476.5625ml) of diluent (water). Mix thoroughly to ensure a homogenous solution.
That's it! You have successfully prepared a 500ml solution of 0.3% chlorine dioxide using 6.4% tablets. Remember to follow safety guidelines and use appropriate measuring equipment for accurate results.
