What should you wear while using hydrochloric acid?
goggles, an apron, and heat proof gloves
What three things should you always do when handling acid or alkali in a lab?
Only three? Wear Goggles Wear protective clothing Have neutralising soluton to hand Plus depending on the reaction to take place - use a fume cupboard or breathing mask, ALWAYS ADD ACID (and alkali) to water, never other way around etc. Some acids are not so much corrosive as highly toxic so again different requirements.
Why should i handle acids carefully?
Depending on the acid and the concentration, there is a danger, when using strong acids, of blindness if splashed in the eyes. Or severe burning if the acid touches the skin. Always wear acid resistant clothing, apron, gloves, etc. and also wear safety goggles. Avoid breathing in any fumes.
What is neutralsation?
its wear you mix acids to alkali

Is acetic acid bad or good?
Acetic acid is commonly known as vinegar. It depends on what you are using it for as to whether it is good or bad. Personally, I love balsamic vinaigrette salad dressing, so I would say it is good. As to it's properties, acetic acid is a weak acid, meaning it will not burn you if you spill it, unlike HCl or H2SO4. Of course, if you are in a lab, you should still wear gloves, etc.

What do you do if you come into contact with acid?
Wash Wounded svrface with Water.. Water acts as Base.. You should NEVER put water on an acid burn. Water may act as a base, but it is in fact slightly acidic itself. If you listened during your chemistry class, you learned that you mix the acid into water, using acid first. If you did it the other way around (using water first) it would cause a sever chemical reaction. Also, there was an accident a few years ago here in America where a girl on a school bus had her head out the window. A chem truck carrying acid had crashed and spilled acid on the road. As the bus when by the scene, some of the acid got on her face and started to burn her face. She then started to cry and her tears made things worse by amplifying the chemical burn. I do agree with the previous answerer in that a BASE should be used to counteract the acid, but it should NEVER be water.
