What compounds is a non electrolyte when pure but an electrolyte when dissolved in water?
A non-electrolyte when pure, but an electrolyte when dissolved in water, is typically a compound that ionizes in solution. An example is acetic acid (CH₃COOH); in its pure form, it does not conduct electricity, but when dissolved in water, it partially ionizes into acetate ions (CH₃COO⁻) and hydrogen ions (H⁺), allowing it to conduct electricity. Other examples include certain organic acids and bases that behave similarly in aqueous solutions.
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?
Hydrogen chloride and hydrogen fluoride are two examples of compounds that are covalent when pure but ionize to give ions when dissolved in water. When dissolved in water, hydrogen chloride forms H+ and Cl- ions, and hydrogen fluoride forms H+ and F- ions.
Is dissolved sugar a mixture or pure substance?
Dissolved sugar is a homogeneous mixture. While sugar is a pure substance in its solid form, when dissolved in water it forms a mixture where the sugar molecules are evenly distributed throughout the solvent.
Which type of liquid is the best conductor of electricity?
waterWater is the best conductor, but not in its most pure form. Pure water or H2O does not conduct electricity well at all. But, many substances dissolve in water. In fact it is known as the "universal solvent". Because of this, water found in nature and in use is rarely pure and will conduct electricity rather well.So, it is the many dissolved compounds in water, not the water itself that conducts electricity well.But normally yes, water it the best liquid conductor.

Is hydrochloric acid a good conductor?
Hydrochloric acid itself is a poor conductor of electricity because it does not dissociate into ions in its pure form. However, when hydrochloric acid is dissolved in water, it forms ions that can conduct electricity.
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.
What properties or factors determine the conductivity of water?
The conductivity of water is determined by the presence of dissolved ions, such as salts and minerals. These ions allow electric current to flow through the water, making it conductive. Pure water, without any dissolved ions, has low conductivity.
Is sodium chloride dissolved in pure water a neutral base?
yes because the two atoms that is sodium which is small in size and chlorine which is highly electronegative can form hydrogen bond not only in between themselves but also with solvent (pure water).
Is hydrogen chloride an ion?
Hydrogen chloride is a covalent molecule composed of hydrogen and chlorine atoms. It does not exist as an ion in its pure form. However, when dissolved in water, hydrogen chloride can ionize to form hydronium (H3O+) and chloride (Cl-) ions.
How can molten NaCl be electrolyzed to form pure Na and pure Cl?
At the positive anode, attrackting negative ions: Two electrons are picked up there from two chlorine ions: 2 Cl- --> Cl2(gas) + 2e-At the negative anode, attrackting positive ions: Two electrons are donated to two sodium ions: 2e- + 2Na+ --> 2 Na(solid)
Is the water a conductor or an insulator?
Water is a fair conductor of electricity due to the presence of dissolved ions and minerals. However, pure water is a poor conductor as it lacks ions necessary for conducting electricity.
