Is pure water a solution?
Absolutely pure water is not even that. Water dissociates itself into dissolved hydroxide and hydrogen ions, the latter forming hydronium. It is thus a solution of both of these ions.
Name two compounds which are covalent when pure but ionise to give ions when dissolved in water?
Many common salts are covalently bound when together but dissolve into constituent ions when dissolved in water. Two examples are sodium chloride and calcium chloride.
Is tetrachloromethane an electrolyte?
Carbontetrachloride, CCl4, is not an electrolyte. To be an electrolyte, the solution must contain dissolved ions. All pure liquids, with only a few exceptions, are not electrolytes.
Is water a conductor of electricty?
Yes and no. Pure water, i.e. distilled or deionized, is a very poor conductor of electricity. However, in most cases water is not pure and has some amount of dissolved ions making it a good conductor.
Does deionised water contain dissolved gases?
No, distilled water is pure water. There is nothing but H2O in it. However, if it is not stored properly, gasses can easily become dissolved in it. due to lack of dissolved gases marine animals do not survive in it...

What is the chemical equation of sulphuric acid producing ions when dissolved water?
pure sulphuric acid was dissolved in water
Is every clear liquid pure substance?
Not always; tap water is clear but contains many dissolved ions.
Can you see hydronium and hydroxide ions in a sample of pure water?
no, because pure water has an even number of H+ ions and OH- ions that have all bonded to form H2O.

Are all pure liquids volatile in nature?
Not always; tap water is clear but contains many dissolved ions.
Why pure sodium chloride a non-conductor but when dissolved in water it is a good conductor of electricity?
They conduct better because then they break up into ions

What makes strong electrolytes?
When substances are dissolved in water they create ions. A strong electrolyte is when separate ions are formed in water. Note that pure water does not conduct electric currents. But ionic water does. A strong electrolyte is merely a collection of ions that interact with each other.
Can hydrogen fluoride be dissolved in pure water?
Yes hydrogen fluoride can be dissolved in pure water.
How many times will the solubility of barium sulfate in a solution of H2SO4 concentration of 0.025 mol / l decrease compared to its solubility in pure water?
Barium sulfate, BaSO4, is a sparingly soluble salt. The solubility of a salt in water depends on the concentration of the ions present in the solution. The solubility of a salt can be affected by changes in temperature, pressure and the presence of other dissolved species. When sulfuric acid (H2SO4) is added to water, it dissociates into two hydrogen ions (H+) and one sulfate ion (SO42-). The H+ ions can then react with the BaSO4 to form Ba2+ and SO42- ions. BaSO4 (s) Ba2+ (aq) + SO42- (aq) The solubility of BaSO4 in pure water is low, but when a strong acid such as H2SO4 is added to the solution, the solubility of BaSO4 is decreased. This is because the H+ ions react with the Ba2+ ions to form an insoluble solid, BaSO4. The solubility of BaSO4 in a solution of H2SO4 concentration of 0.025 mol/L will decrease compared to its solubility in pure water, because the H+ ions from the H2SO4 are reacting with the Ba2+ ions to form an insoluble solid, BaSO4. In other words, the added H2SO4 makes it more difficult for the BaSO4 to remain dissolved in the solution. It's important to note that the solubility decrease will depend on the concentration of the acid, the temperature and the presence of other dissolved species.
