Yes, this is one of the many dirty little secrets of chemistry: There isn't any such thing as pure liquid water. Distilled water is a very dilute solution of hydroxide and hydronium ions, because (like many other solvents) water reacts with itself:
2 H2O() H3O+(aq) + OH-(aq)
At room temperature, about 1 in every 10 000 000 water molecules has dissociated by donating a hydrogen atom to another water. Distilled water under these conditions is actually 10-7MH3O+ and 10-7M OH-.
Hydroxide ion is the caustic component of lye, and hydronium ion makes acid solutions corrosive. However, the concentrations in water are extremely low and not at all dangerous. (For an opposing opinion about the toxicity of water, click here.)
Distilled water also reacts with atmospheric carbon dioxide according to
H2O() + CO2(g) H2CO3(aq)
H2CO3(aq) + H2O() H3O+(aq) + HCO3-(aq)
HCO3-(aq) + H2O() H3O+(aq) + CO32-(aq)
which brings the pH of distilled water in an open-air container down to about 5.8.
Mineral contain is very less
Sodium chloride (NaCl) in water is a true solution.
Distilled water in a compound.
None of these. Water is a compound, which is a pure substance.
colloidal soln
No, because the sand particles do not dissolve and in time will settle at the bottom making it a suspension.
YES!!!!!!!!!!!!!!!!
It is a suspension.
Kerosene is a colloid. :))
Solution
It is a suspension.
No. A colloid is a suspension of solid particles in a liquid medium. Salt is not suspended in water, it dissolves.
Sodium chloride (NaCl) in water is a true solution.
Soda water is a solution of water and carbon dioxide gas.
Distilled water in a compound.
colliod
None of these. Water is a compound, which is a pure substance.
Solution actually. Cordial is itself a solution, so adding water to it just changes concentration.
