I think, the best way to check water is the use of a hydrometer. Pure (distilled) water has a Specific Gravity (SG) of 1.000. So check it with a hydrometer, if it's SG is one than it is distilled water otherwise contaminated.
No, unless you order online which can be very expensive and not of good quality..
Distilled water. It has less bacteria and chemicals in it than tap water.

Distilled water is simply purified water.
In a pinch, you can use tap water in a lead-acid battery. Since the minerals dissolved in the water will eventually poison the battery it isn't advisable to make a habit of it. If your reverse osmosis device removes most of the minerals you can probably substitute it for distilled water but you should confirm the quality of the water it produces before making a habit of it. A quick method to check the quality would be to check the water's conductivity. Using an Ohm meter, compare its conductivity to that of distilled water at the same temperature. If the measurements are close then have at it.

You should not drink distilled water as it lacks minerals which are beneficial for us.Make a solution of the salt in distilled water.
It should not, mine doesn't. If yours does so then seek medical advice or check your water.
Distilled water is neutral
Water (distilled or not) is a chemical compound - H2O.
distilled! :D
