The given substance Na 2 CO 3 is a strong electrolyte, weak electrolyte, or nonelectrolyte has to be identified. Concept introduction: Electrolytes: Ionic compounds dissociate in to two different ions like cation and anion, therefore its conduct the electricity. Ionic compounds are electrolytes, because it conducts an electric current when dissolved in water. Strong electrolyte: A compound that completely dissociates into its ions in aqueous solution. Strong acids and strong base are strong electrolyte because, they ionize completely. Weak electrolyte: A compound that dissociates partially in an aqueous solution. Aqueous solutions of weak electrolytes conduct less electricity. Weak acids and weak base are weak electrolyte because, they do not ionizing completely. Nonelectrolyte: Nonelectrolytes are not ionizing compound molecular compound. They do not conduct the electricity.

Solution Summary: The author explains that Ionic compounds are electrolytes, because they conduct an electric current when dissolved in water.
The given substance Na2CO3 is a strong electrolyte, weak electrolyte, or nonelectrolyte has to be identified.
Concept introduction:
Electrolytes:
Ionic compounds dissociate in to two different ions like cation and anion, therefore its conduct the electricity. Ionic compounds are electrolytes, because it conducts an electric current when dissolved in water.
Strong electrolyte:
A compound that completely dissociates into its ions in aqueous solution. Strong acids and strong base are strong electrolyte because, they ionize completely.
Weak electrolyte:
A compound that dissociates partially in an aqueous solution. Aqueous solutions of weak electrolytes conduct less electricity. Weak acids and weak base are weak electrolyte because, they do not ionizing completely.
Nonelectrolyte:
Nonelectrolytes are not ionizing compound molecular compound. They do not conduct the electricity.

Write the reagents required to bring about each reaction next to the arrows shown.
Next, record any regiochemistry or stereochemistry considerations relevant to the
reaction. You should also record any key aspects of the mechanism, such as forma-
tion of an important intermediate, as a helpful reminder. You may want to keep
track of all reactions that make carbon-carbon bonds, because these help you build
large molecules from smaller fragments. This especially applies to the reactions in…
