Hi I want to make a hydrochloric acid i heard you can make it with salt and vinager. Could some one tell what the proportions are for that and i what precautions i should to take to handle and dispose of it. im just using it to clean pennies as an experiment im new to chemistry and thats all i have availbable right now. i also need to know how to check for purification too thanks to all in advanced:-)

Hi Im fifteen and I just started to get into chemistry really seriously just a few days a go to be honost. I found this website and this is what made me realize I really wanted to go into chemistry as a major. If any one could give me advice on experiments I could do or advice on chemistry I cant take it in school yet and I have overly worried parents so the experiments cant be anything spectacular until I take a chemistry for a while at school.
