Lighter ions have higher mobility and in turn conductivity. Higher charge on ions will have more current carrying capacity. Hello Abbas, First concerning your question why CaCl2 is better than NaCl: upon dissociation you get three ions Ca2+ and 2 Cl– while NaCl provides you with only two ions.
Why does NaCl have a higher conductivity than CaCl2?
Because NaCl has two ions, CaCl2 has 3 ions, and AlCl3 has 4 ions, AlCl3 would be the most concentrated with the highest conductivity and NaCl would be the least concentrated with the lowest conductivity.
Is calcium or sodium more conductive?

Is NaCl the best conductor of electricity?
For the ‘conduction of electricity’, the element or compound must have free moving electrons or ions. NaCl is a “good conductor of electricity” in molten state but not is solid state.
Is NaCl conductive?
NaCl solutions have electrical conductivity because the NaCl solutions is a strong electrolyte in which the constituent ions dissociate entirely so that in NaCl solutions there are free-moving ions.
Can NaCl conduct electricity?
Solid sodium chloride does not conduct electricity, because there are no electrons which are free to move. When it melts, sodium chloride undergoes electrolysis, which involves conduction of electricity because of the movement and discharge of the ions.
Is calcium a 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.
Is NaCl more conductive than KCl?
The electrical conductivity of KCl was higher than NaCl. The electrical conductivity increased with the increase in concentration of NaCl and KCl, while a reverse trend was observed for the molar conductivity.
Is calcium a good conductor of electricity and heat?
Calcium is classified as a solid and metal. Like most metals, calcium is a relatively good conductor of heat and electricity.
Is CaCl2 a strong electrolyte?
When calcium chloride dissolves in water it breaks up into its respective ions, ( charged particles) one mole of CaCl2 breaks up into one mole of a Ca+2 ion and 2 moles of Cl-1 ions thus it is a strong electrolyte and will conduct electricity when dissolved in water.
Is ammonium chloride conductive?
The conductivity of ammonium chloride is significantly greater than that of a comparable alkali chloride and reasons are given for believing that a conductivity mechanism operates in the ammonium salt which is not possible for the alkali metal salts.
Is CaCl2 ionic or covalent?
CaCl2 or Calcium Chloride is an ionic bond and not a covalent bond. Since there should be sharing of electrons between two atoms to be a covalent bonding. In case of calcium chloride, the calcium gives up an electron to each chlorine atom, becoming Ca2+ ions and chlorine become Cl– ions.
Why is NaCl a good conductor of electricity in molten state?
As the motility of individual atoms or molecules in liquid state is far greater than solid, the ions (Na+&Cl−) are free to move and therefore can act as charge carriers. Hence molten sodium chloride is a good conductor of electricity because of free ions.
Which compound would be the best conductor of electricity?

| 1 | Silver (Pure) |

| 2 | Copper (Pure) |
| 3 | Gold (Pure) |
| 4 | Aluminum |
| 5 | Zinc |
Is NaCl an insulator or conductor?
For example, solid sodium chloride (NaCl, or table salt) does not conduct electricity; it is an insulator. If NaCl is placed into water, the mutual attraction both sodium (Na) and chlorine (Cl) have for water molecules cause their bonds to break (dissolving) and form ions (charged atoms or molecules) within the water.
Is NaCl a strong electrolyte?
Hydrochloric, nitric, and sulfuric acids and table salt (NaCl) are examples of strong electrolytes. Weak electrolytes are only partially ionized, and the fraction ionized varies inversely with the concentration of the electrolyte.
What is the conductivity of 1M NaCl?

| Industrial Wastewater | 5,000 |
| Seawater | 50,000 |
| 1M NaCl | 85,000 |
| 1M HCl | 332,000 |
Is NaCl ionic or covalent?
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
Why is NaCl a bad conductor of electricity in the solid state?
Solid [NaCl] is a bad conductor of electricity because the charged particles (ions) in solid [NaCl] are not capable of moving as they are bound by strong electrostatic forces. As a result, they can not conduct electricity.
Is sodium hydroxide a good conductor of electricity?
In solid state, sodium hydroxide cannot conduct electricity as the ions are not free to move. They are tightly packed in the crystal lattice and are localized. At the best, they can vibrate around their mean position. Since there is no movement of ions, there is no electrical conductivity in solid sodium hydroxide.
