Vitamin C To Dechlorinate Water: How Much?

The amount of vitamin c needed to dechlorinate water depends on several factors such as the type of chlorine being used, the size of your tank, and other environmental conditions. You need to consider these factors when deciding what amount of vitamin c you’ll need for your project.

How Much Vitamin C Do I Need To Remove Chlorine From Water?

To remove chlorine from water, you need to add it to the water first. Once added, it’s very difficult to get rid of it completely. If you’re using sodium hypochlorite (NaOCl), then adding enough salt (table salt) will make sure that there isn’t any residual chlorine left after the addition of the NaOCl.

If you’re using potassium dichromate (K2O), then you’ll have to use some sort of chemical reaction to break down the K2O into its constituent parts.

In either case, once the chlorine is removed, it needs to be replaced with fresh water or treated with bleach before drinking. There are many different types of chemicals that can be used for this purpose. We’ll talk about two of them: sodium thiosulfate (Na2S2O3) and sodium thiopental (NaC11H13Cl3).

Vitamin C For Chlorine Removal – Sodium Thiosulfate

The first thing you need to do is mix a solution of 1.00 grams of sodium thiosulfate in 500 milliliters of water. Then, take 16.00 grams of table salt and mix it into the solution.

This is a pretty large amount of thiosulfate and salt, and it’s unlikely that you’ll have this amount lying around your house. If you don’t have the materials or the time to mix the chemicals, then there are many online resources that sell sodium thiosulfate at an affordable cost. We don’t recommend using anything but pure sodium thiosulfate for this process!

Once mixed, pour all of the liquid into your water container. You’ll see that the water will start to bubble and fizz, releasing a gas into the air. Wait about an hour for the reaction to finish, then check the water to make sure that the chlorine has been neutralized.

If it hasn’t, then you need to perform the steps again.

Vitamin C To Dechlorinate Water: Sodium Thiopental

Prepare a solution of 0.5M sodium thiopental in your container of choice. Take a pH reading with your pH strip.

If the pH is less than 11, add 1M sodium thiopental and stir until the liquid is clear. Take a new reading and continue this process until the pH is at exactly 11.

While stirring, slowly drip in 3mL of 35% hydrogen peroxide. When all the hydrogen peroxide has been added, take another pH reading. It should be under 11.

If not, slowly drip in more 35% hydrogen peroxide until the pH falls under 11.

Let the container sit for up to an hour before checking the pH again. If it is under 11, you are finished. If it is not under 11, continue dripping in small amounts of 35% hydrogen peroxide until it is under 11.

You may need to wait ten minutes between each drip to let the reaction finish occuring.

Finally, once the chemical has been fully neutralized, add 1M sodium thiosulfate until the solution becomes clear. Add water to dilute to taste.

What Is The Best Way To Store Dechlorinated Water?

Storing water is a very straightforward process. If you plan on drinking the water the same day then storing it in a clean glass bottle that’s been washed in hot water with detergent is fine.

If you’re going to be storing the water for a long period of time then it is best to use plastic bottles or a simple bucket and use a standard water preserver. These are widely available in most supermarkets and hardware stores.

Is It Possible To Overdose On Dechlorinated Water?

The short answer is no, it isn’t possible to overdose on de-chlorinated water.

Can I Use This Same Trick To De-Chlorinate Other Chemicals?

While you can de-chlorinate other chemicals like bleach, it isn’t recommended. The process is very different and requires a much higher level of toxicology knowledge that you most likely don’t have. De-chlorinating water is one of the safest chemical processes that you can do at home, but de-chlorinating anything else is more dangerous.

Do You Need To Use A Scale To Do This Process?

While it can be helpful to weigh things, you can measure out the chemicals using normal measuring cups and the process is exactly the same. The reason for weighing things is to make sure that you’re using an accurate measurement. If you’re careful and able to measure accurately without a scale then you don’t need to spend the money on one.

What Else Can I De-Chlorinate With This Method?

This is a very good question and the answer is yes, almost anything. While chlorine was used in this example, there are many other types of dangerous elements and compounds that can be neutralized in this way.

One note of warning though is that some organic compounds can be broken down or even create other harmful byproducts when exposed to extreme levels of heat or strong acids. Always make sure to test the process on a small scale before executing it on a larger scale.

If you know the compound that you’re trying to de-chlorinate, you can search online to see if it’s dangerous and what sort of safety gear you should be using when handling it. Follow those safety guidelines and use the same process as you did with chlorinated water and you should be fine.

Where Can I Find More Information About Chemicals?

There are many great sources of information online about various chemicals and their safety guidelines. A few places to start are: REACTS is a database put together by NTP (National Toxicology Program) which lists the potential health effects of many different compounds.
