an electrolyte
because of the gravity or Magnetricity
When an ionic compound dissolves in water there are free ions which move and carry electric current.
because when the ions can move around freely, they can conduct electricity better
Yes, it will conduct electric current much better than plain water. The sugar molecules in water form a clear solution by ionization facilitating the path of electrons of electric current.
i don't know ( In the book )
Aluminium foil and potassium hydroxide in water solution are conductors.
In solid state the ions are packed very tightly, so ions are not free to move, therefore no conduction.
Yes it does.
These are the ionic substances.
Electrolyte
That depends on the kind of polution. If it is polution with (for instance) pure sand or sugar it does not conduct electricity. These kinds of polution do not decompose when dissolved. If the polution consists of salts that are dissolved in the water, than it certainly does conduct electricity. This comes from the fact that the dissolved salt decomposes in positive and negative ions. If an electric current is plave inside the basin, these ions will travel to the opposite electric pole. This movement of charged particles is an electric current. It is hard to say if the current travelling through poluted water is dangerous, or not. This depends of course on the strength of the current as well as the concentration of the polution.
Yes, test with a electric multy meter
