How to Make Salt (Using Bleach and Vinegar)

Ammonia can be a substitute for bleach. 


Step 1: Gather Materials

-Two flasks made for chemistry purposes


-Bleach (or ammonia) 

-1 balloon


Step 2:

Put all your materials aside except for your sodium and one of the flasks. Remove one piece of sodium from it's bottle, dry off the oils with a towel or napkin (Make sure to touch the soidum as little as possible) and place it into the flask. Set this flask aside. 

Step 3:

Using the second flask, open the vinegar and pour about 1/2 of a cup into the flask. Make sure to shut the vinegar, you won't need it anymore. 

Step 4:

Now with the flask of vinegar, get your bleach (or plain ammonia) and balloon ready. As soon as you pour 1/2 cup of bleach into your flask, cover it with a balloon. Tihs way, you can gather the chlorine gas you just made. 

Step 5:

Pinch off the end of the balloon with one hand, and remove it from the flask. Make sure to pinch the balloon tightly so none of the chlorine gas you just created escapes the balloon. 

Step 6:

Take the first flask you used, containing a piece of sodium, and cover the flask's lid with the balloon. At this point, you should have a reaction that creates salt. 

This hasn't worked for us yet, but these are the steps we have gone through to create chlorine gas. We have tried both bleach and ammonia.

    This is interesting but a bit scary playing with chlorine gas and sodium metal.

    sorry about posting that so many times i was posting it and it didnt post so i kept on praesing post and it posted so many times

    I believe the attempt was to prepare a bit of Chlorine gas from bleach (not ammonia). Depending on the type of bleach, it contains sodium hypochlorite or similar molecule. Recheck your Lewis Structures and chemical formulas! Sweet that you got so many comments!

    Anyone who doesn't know enough chemistry to realise that you can't get chlorine from ammonia and vinegar should not be playing about with sodium metal. I would assume your teacher gave it to you, in which case he should have known better ( or should have taught you better ). The correct procedure for making sodium chloride is to ignite a small piece of sodium on a deflagrating spoon and quickly put it inside a gas jar filled with chlorine. The sodium will burn vigorously producing a white cloud of sodium chloride.

    I felt mislead when it says how to make salt. Its also an unfinished project

    My Chemistry class required us to create an instructable to show the steps we took in order to complete our experiment, whether it worked or not, so he could understand what we did right and wrong. Innovative learning and all that jazz.

    The materials involved in this are potentially dangerous, as is the reaction that is being attempted. The instructable should include a warning and information about proper safety while attempting this procedure.

    As the matthatter said, ammonia cannot be substituted for bleach - there's no chlorine in either ammonia or vinegar, so there is no way a reaction between the two can create chlorine gas.

    The matthatter's suggestion about melting the sodium should work, but I wouldn't attempt mixing sodium and chlorine in this setup. The reaction is very exothermic (heat-producing) and would be dangerous in this setup.

    How is ammonia going to create chlorine gas when mixed with vinegar? NH3 + H2O and CH3COOH ???? If you can pull that off you might be able to turn lead into gold.
    Once you get your Chlorine, you will need to heat the sodium up
