Answer 1

Answer:

On passing electric current through the solution, ions move ... According to strength ionic conductors are of 2 types : ... (b) 50 mL of 0.2 M NaOH + 100 mL of 0.1 M RbOH the resulting solution is diluted ...

Answer 2

Aqueous solution is the best conductor of electric current of 0.1 M NaOH

Explanation:

• When passing electric current through the solution, ions move from one end to the other.
• According to strength of ionic conductors they are of 2 types
• 50 mL of 0.2 M NaOH + 100 mL of 0.1 M RbOH the resulting solution is diluted .
• NaOH is strong base,and it is completely dissociated and thus gives Sodim ions Na+ and Hydroxide OH- ions.
• This helps in conducting electricity and among the given  4 options
• 0.1M NaOH is strong base and hence, it is best aqueous solution which is used for conduction of electricity.
