STANDARD Chemistry Electrolysis MCQ Question
Type: MCQ-conceptual-Medium-Class 12
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.
Correct Answer
Option D
Detailed Explanation
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.
