Why did the solutions conduct electricity and not the solid substances?
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
Why can ionic solutions conduct electricity when in solution but not solid?
Ionic substances will not conduct electricity as solids. This is due to the fact that ions are not free to move in a solid as they are arranged in an ionic lattice. When an ionic substance is dissolved in solution or molten the ionic lattice is broken down allowing the ions to move freely and so conduction occurs.
Why is calcium oxide a good conductor of electricity?
Explanation: As for calcium oxide, the more electrons not firmly locked to other bits of the material the more conductive it is.
Why does solid calcium conduct electricity whereas solid calcium chloride does not?
Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current .
Why ionic solids do not conduct electricity in solid state even though their crystal lattice consists of ions?
In the solid state, electrostatic forces hold the ions together in a crystal lattice structure, which is, in short, a 3D interconnected ion network. A solid ionic compound does not conduct electricity because the ions are not free to move.
Why do electrolytes conduct electricity and Nonelectrolytes do not?
Electrolytes are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity. Nonelectrolytes do not dissociate into ions in solution; nonelectrolyte solutions do not, therefore, conduct electricity.
How is it that ionic compounds in the solid state do not conduct electricity but they do?
The ionic compounds in solid state are bonded with strong intermolecular forces and are not free to move. Therefore, they cannot conduct electricity. However, when this salt melts, its constituent ions are separated from each other and become free to move across the melted salt that can conduct electricity.
Why do ionic compounds conducts electricity in molten state whereas not conducts electricity in the fused state?
Ionic compounds conduct electricity in solution because they are made up of electrically charged ions but covalent compounds are made up of electrically neutral molecules so they do not conduct electricity. Hence ionic compounds conducts electricity in molten state and does not conducts electricity in the fused state.
Why can dissolved ionic compounds conduct electricity but most covalent compounds Cannot?
When a covalent compound dissolves in water, it does not dissociate into ions. Because there are no free electrons or ions in the water (electrolytes) dissolved covalent compounds can’t conduct electricity.
Is calcium oxide a good conductor of electricity?
It is known that calcium oxide is a dielectric material; its electrical conductivity is about 10 − 8 S/cm at 1050 K (777 • C)  , which is almost 5 orders of magnitude less than that of CZS.
Is calcium oxide a solid?
Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide.
Is calcium a good conductor of electricity?
Calcium is harder than lead but can be cut with a knife with effort. While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor by mass than both due to its very low density.
Why can both calcium chloride solution and solid calcium conduct electricity?
It has ionic bonds and it is the property of ionic compounds that they conduct electricity when dissolved in water. So solution of calcium oxide conduct electricity.
Can calcium conduct electricity in a solid state?
Calcium is classified as a solid and metal. Like most metals, calcium is a relatively good conductor of heat and electricity.
What type of crystal does not conduct electricity as a solid but will conduct electricity when dissolved in a solution?
Generally, ionic crystals form from a combination of Group 1 or 2 metals and Group 16 or 17 nonmetals or nonmetallic polyatomic ions. Ionic crystals are hard and brittle and have high melting points. Ionic compounds do not conduct electricity as solids, but do conduct electricity when molten or in aqueous solution.
