sugar and salts*
Yes it willl... But water will dissolve more amount of salt than ethanol..... U can see google .... Fr explanation
How much salt is required to add into it?
Not fixed...
Water will dissolved a large amt than alcohol
A second test will be
Keep a plant in it fr sm days..... It will survive if it is water only
I am sorry, but International Organisation for Chemical Sciences and Development doesn't allow any kind of such inaccurate and unappropriate measures for testing of pure Water.

We will add a few drops of litmus solution to it. If the litmus solution doesn't change its colour to red or blue, that will indicate that the solution is neutral, which is most probably is pure water.
Pure water doesn't allow electricity to pass through. If we connect the contain with pure water to a circuit, it will not conduct electricity.
The boiling and freezing point of pure water are 100 and 0 degree Celcius respectively.
The vapours of water has no colour, smell or taste.
By keeping the crystals of Anhydrous Copper Sulphate in the vapours of water, its colour will change from white to blue due to hydration.
