Why does solid and molten calcium chloride have different electrical conductivity?

Calcium looses 2 electrons and 2 chloride ions accepts the electrons to form the ionic compound. Aquaous and molten calcium chloride had mobile ions and this is what is responsible for the electrical conductivity. Most of the ionic compound conduct electricity while in the molten state.

Why does calcium chloride conduct electricity when molten but not solid?

Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current . But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.

Why does solid and molten calcium chloride have different electrical conductivities?

shr · Dwayne M. Becca M. Solid ionic compounds do not have electrical conductivity because the ions are not free to move. In a liquid, the ionic compound dissociates into its respective ions.

Why does calcium chloride conduct electricity when melted?

Molten Calcium chloride and molten Magnesium chloride contains Calcium ions and chloride ions,magnesium ions and chloride respectively . These ions are mobile hence they conduct electricity. carbon tetrachloride and silicon tetrachloride have no mobile ions and therefore they can‘t conduct electricity.

Does calcium conduct electricity when molten and solid?

It is also found within “hard” water. Calcium is classified as a solid and metal. Like most metals, calcium is a relatively good conductor of heat and electricity.

Does calcium chloride conduct electricity as a solid?

The density of calcium chloride is 2.15 gm/cm3. It is soluble both in inorganic solvents like water, as well as organic solvents like ethanol. Usually in a molten state, it is a good conductor of electricity. Calcium chloride is a bad conductor of heat.

Why does diamond not conduct electricity but is very strong?

Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. As a result, diamond is very hard and has a high melting point. … It does not conduct electricity as there are no delocalised electrons in the structure.

Which object is the best conductor of electricity?

Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.

Why Carbon tetrachloride is a liquid but does not conduct electricity?

Carbon tetrachloride is a liquid and does not conduct electricity because it is a covalent compound and there no free ions present and contain only molecules.

Why does lithium fluoride conduct electricity when molten but not solid?

Lithium oxide only conducts electricty in its molten state. It is an ionic compound and in solid Li2O the ions are fixed in position in an ionic lattice, the ions are not mobile and therefore cannot conduct electricty.

Is calcium chloride conductive when dissolved in water?

If an ionic compound is dissolved in water, it dissociates into ions and the resulting solution will conduct electricity. Although calcium chloride and sodium chloride are considered to be non-hazardous, unpredictable reactions among chemicals are always possible.

Does calcium chloride conduct electricity dissolved in water?

About Calcium Chloride

Calcium Chloride is an excellent water soluble crystalline Calcium source for uses compatible with chlorides. Chloride compounds can conduct electricity when fused or dissolved in water. … Calcium Chloride is generally immediately available in most volumes.

Does solid calcium chloride has a low melting point?

Calcium chloride, CaCl2, is a typical ionic halide and is a solid at room temperature. Its molecular weight is 110.98 g/mol and its melting point is 772 °C. Very few natural minerals occur.

Is calcium a good conductor of electricity?

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 is seawater a better conductor of electricity than freshwater?

Deionised water by its nature has very few ions. … Sea water has a relatively large number of Sodium and Chloride ions and has a conductivity of around 5S/m. This is because the Sodium Chloride salt dissociates into ions. Hence sea water is about a million times more conductive than fresh water.

Is magnesium a good conductor of electricity?

Magnesium. Magnesium is not an especially good conductor, being less conductive than aluminum but it is lighter. It has some other major drawbacks which make it completely unsuitable for use in electrical installations.
