Salt & Vinegar
I have heard from a few different places that mixing lots of salt with vinegar somehow makes Hydrochloric acid and im guessing sodium acetate.
I tried this a few months ago and i added hydrogen peroxide because i was trying to make rust.
I was just going to use the vinegar/H2O2 to make it but i added salt thinking that it would make it stronger.Now that i have been trying to filter
the rust out the solution is a sort of dark amber color its not cloudy it is definitely a skin irritant. I think its iron chloride but im not sure.

I've read that, too, but only in children's books. It's not true. Adding salt to vinegar will make it slightly more corrosive to metals and metal
oxides because the chloride ion will tend to coordinate to the metal ions and help solubilize them.
What you have in your solution is probably a mixture of iron(III) ions, some of them partially hydrolyzed, others possibly coordinated by chloride.
If you add a small amount of baking soda, that should precipitate the iron out as rust.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

You mixed salt (NaCl, I assume), vinegar, and hydrogen peroxide, and tried to filter out rust (Fe2O3, I presume); where did the Fe come from? Are you
claiming to have effected a transmutation of elements?

CharlieA The iron came from some steel wool, a chunk of old iron(dont know what it is) and nails. I have already added sodium bicarbonate which
precipitated the other stuff.

Nuts! I thought you were on to something that the alchemists missed! What are your
plans for the rust?

I agree with DraconicAcid. But I can not understand why (some) books say that.
