Question

Which of the following statements is true?

• A. When an aqueous solution of $NaCl$ is electrolysed, sodium metal is deposited at cathode
• B. There is no difference between specific conductivity and molar conductivity.
• C. Silver nitrate solution can be stored in a copper container
• D. The addition of liquid bromine to iodide solution turns it violet.

Answer 1

Answer: (D)

The addition of liquid bromine to iodide solution turns it violet.

Answer 2

When an aqueous solution of NaCl is electrolysed hydrogen is liberated at cathode. Specific conductivity and molar conductivity are different terms. Silver nitrate solution cannot be stored in a copper container as silver will get precipitated because of high reactivity of Cu than Ag.

The addition of liquid bromine to iodide solution turns it violet.
