Which solution is a good conductor of electricity?

Which solution is a good conductor of electricity?

Solution : Salt solutions are good conductor of electricity due to the formation of mobile ions.

When dissolved in water the solution is a good conductor of electricity ionic or covalent?

When dissolved in water, sugar molecules separate from each other and diffuse throughout the solution, but their chemical identity is unchanged. No ions are released into the water, so its conductivity is unchanged. Water is also a covalent compound and is a poor electrical conductor.

How do you tell if a substance is a good conductor of electricity?

Compounds with Strong Conductivity The easiest way to determine whether a compound can conduct a current is to identify its molecular structure or composition. Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water.

Which of these substances would be a poor conductor of electricity?

Explanation: In the given options water and sugar would be the poor conductor of electricity. Other given options such as water and salt, water and Hcl and water and NaOH are better conductor of electricity because Hcl ,NaOH, salt (Nacl) can break into their ionic form whereas water and sugar will not.

Why salt water is a good conductor of electricity?

o Ask the students: “Why did the salt make the water more conductive to electricity?” (The molecules of salt dissociate into ions of opposite charges. It is the ions that render the water conductive to electricity. In our experiment, the Na+ and Cl- ions made it possible for the distilled water to conduct electricity.)

Is Salt a conductor or insulator?

Salt itself is an insulator of electricity. The conductivity of any solution depends on the movement of ions. Ions are the charged species of the atom. In salt the movement of these ions are not possible.

Is Salt a poor conductor of electricity?

Dry salt is a poorest conductor of electricity. But, salt mixed with an aqua is most best conductor of electricity . Salt is made up of Na+ and Cl- ions.

Is lemon juice a conductor or insulator?

Lemon is basically a citrus fruit, which contains an appreciable quantity of citric acid. This acid furnishes H+ ions, and we know that motion of ions (charged species) causes the flow of current. Thus, lemon juice is a good conductor of electricity due to the presence of H+ ions.

Is Vinegar an insulator or conductor?

Vinegar is an insulator or very poor electricity conductor because it lacks free ions. It’s an acetic acid which is a weak acid, this conducts electricity poorly.
