The Electrical conductivity of an aqueous solution depends on the concentration of which particles in the solution
2 answers:
Answer: Option (4) is the correct answer.
Explanation:
When a solution contains number of ions then this type of solution is able to conduct electricity.
For example, when NaCl is dissolved in water the NaCl dissociates into and
ions. Hence, flow of these ions will be responsible for electrical conductivity.
Whereas flow of electrons in a conductor is responsible for electrical conductivity but in a solution ions are responsible for the flow of electrical current.
Thus, we can conclude that the electrical conductivity of an aqueous solution depends on the concentration of which particles in the solution ions.

Explanation:
The Grignard reaction is a very important organometallic chemical reaction where the Grignard reagent ( alkyl, vinyl, or aryl-magnesium halides) acts as nucleophile in order to the formation of Carbon-Carbon bonds.
In the problem, the phenylmagnesium chloride is the grignard reagent. The volume of 2.0 M phenylmagnesium chloride solution you need to add 2.9 mmol is:
2,9 mmol × = <em>1,45 mL</em>
