covalent compounds can carry a charge when dissolved in water because ions separate and can carry a charge.
No, generally not.
Their conductance of electricity in aqueous solutions prove that they are ionic in nature.
- Low melting and boiling points - Don't dissolve easily in aqueous solutions - Don't conduct electricity
They can't. There must be an electrolyte mixed in. For example distilled water doesn't conduct electricity and it is a polar covalent compound. However, when you mix in salt, it does conduct electricity.
The answer is: They increase the concentration of hydroxide ions in aqueous solution.
Aqueous solutions are solutions in which water is the solvent. Anything that dissolves in water forms an aqueous solution.
Aqueous [note spelling] solutions of ionic compounds conduct electricity, but aqueous solutions of molecular compounds do not, unless the molecular compounds dissociate into ions when dissolved. Sugar, acetone, ethanol, and methanol, for example, do not dissociate, but acetic acid does.
Anything metallic can conduct electricity. Also molten ionic compounds and solutions of ionic compounds. Aqueous acids also conduct electricity.
Their conductance of electricity in aqueous solutions prove that they are ionic in nature.
Ionic compounds dissociate in water to form positive and negative ions in aqueous solution. Such solutions can conduct electricity.

Usually, solid ionic compounds are weak conductors of electricity. Aqueous solutions of ionic compounds are good conductors though as they have free ions for conductivity. When table salt is dissolved, the solution conducts electricity well.
Copper II chloride (CuCl2) is an ionic compound because copper is a metal and chloride is a non-metal. Like all ionic compounds in aqueous solutions (i.e., dissolved in water), it conducts electricity.
Ionic compounds conduct electricity in aqueous solution or molten state. In aq. soln. or molten state, ionic compounds dissociate to release respective ions. These ions, being electrically charged, conduct electricity.
The answer is: They increase the concentration of hydroxide ions in aqueous solution.
Hydrogen containing covalent bonds interact with water strongly enough that their molecules dissociate into ions. In aqueous solutions, they are called acids. Examples are Hydrochloric acid (HCl), Nitric acid (HNO3), and Sulfuric acid (H2SO4).
