You need a 3 conductor wire with ground. For example if you had a 30 amp breaker for that outlet you would need 10awg 3w/ground. That's 10 gauge 3 conductor with ground and replace the old wire back to the panel.
YES - it will work fine, and hopefully you have grounding in the plug. If you do not, you should also get surge protection and a safety cap when not using. The 3 prong will not create a ground, so it will not change the fact that it is dangerous not to have ground (you know kids and outlets).
Simply put, it is any electrical outlet the has three holes that the female end plugs into. What this is referred to most of the time (but not always) is a regular 110V outlet. Older outlets had only two holes, one for the hot, one for the neutral. All newer installations have the third hole for the ground wire.
Guessing you are replaceing an outlet? Black goes on the copper colored terminal and white on the same side that has the ground terminal. If you have checked and made sure that white is in fact the neutral you can run a jump wire from the side terminal to the ground. This will ground whatever you plug into the outlet as long as it has a 3 prong plug.
No. You can't replace a 220V outlet with a 110/220V outlet without running the requisite neutral wire. If you do you will blow out any device that expects the neutral line to be connected.

Ground wire is loose or disconnected somewhere in that circuit.
Assuming the wiring to the outlet has 2 loads and one neutral, isolate one load from the outlet and use the neutral as the common. be sure to ground from the receptacle to your conduit or ground lead. You should also replace the corresponding breaker with a 120 volt single breaker.
There is no switch on an outlet. You can mount an outlet with the ground up or down. Most electricians I know mount the ground down as I do.
the bare copper is always a ground
If the wiring system into which you are installing an outlet has no ground available, use an ungrounded outlet. In an ungrounded system, an outlet with a ground contact would allow the outlet user to mistakenly, and perhaps dangerously, assume that a ground was present. A suitable ground may be available as a ground wire accompanying the hot and neutral wires in the cable, or a ground may be available via conductive conduit and a metal outlet box. In any case, use a tester to confirm the integrity of the assumed ground. A voltage test from the hot wire to the ground should show the same voltage as between hot and neutral (the black and white wires respectively). If you are replacing an ungrounded outlet, you need not assume there is no ground present. You may find, in the box, ground wires that were not connected to the outlet. You may come across grounded outlets that have no ground wire attached because they rely on grounding via the mounting screws through the outlet ears to the metal box. This is a less reliable grounding method. It is better to buy a ground-wire "pigtail," fasten the wire directly to a hole in the metal box with the supplied screw, and attach the other end of the ground wire to the outlet via the outlet's ground screw.
There are tow places to put a Ground Fault Circuit Interrupter. There is a GFCI breaker which would be installed in a breaker box and a GFCI outlet that can be installed anywhere. Most GFCI outlets allow you to connect regular outlets to the GFCI and those outlets will also be protected.

Actually they have 3. A round ground, wide neutral, and narrow hot. If it only has 2 it is an old outlet with no ground wire. If that is the case in your home, I highly suggest you connect a jumper wire from the ground screw to the white neutral wire on the silver screw to provide some protection. Do this at every outlet in the home. Replace all the outlets in your home with new ones if they are so old they do not have a ground connection.
You can get a tester that plugs into the outlet at any home improvement store.
A spray tan machine needs an outlet with a ground so that electrocution does not occur. The outlet must supply at least 110 volts. A standard outlet with a ground installed should suffice.
