Question

Which of the following statement(s) are true?
a. Galvanic cell converts electrical energy into chemical energy.
b. Gold-198 is used in the treatment of cancer.
c. The anode is positive in an electrolytic cell.
d. Salt bridge connects electrolytes of two half-cells.

Answer 1

$\bullet$ Galvanic cell converts chemical energy into electrical energy. So, statement a is incorrect.

$\bullet$ Gold-198 is used in the treatment of cancer. So, statement b is correct.

$\bullet$ The anode is positive in an electrolytic cell while the cathode is negative. So, statement c is correct.

$\bullet$ The electrolytes of half-cells are connected through a tube containing a saturated salt solution called salt bridge. So, statement d is correct.
