Question

Students are attempting to construct a battery in the laboratory that will light up a light bulb. Compare the following lists prepared by students and determine which student will not be able to successfully build a "battery" that will light up the bulb.

Select one:

a. Student 1

large beaker

strip of aluminum metal

strip of silver metal

sodium nitrate solution

aluminum nitrate solution

a porous membrane

a length of copper wire

light bulb

b. Student 2

2 beakers

strip of magnesium metal

strip of nickel metal

magnesium chloride solution

nickel(II) chloride solution

potassium chloride salt bridge

a length of copper wire

light bulb

c. Student 3

2 beakers

strip of zinc metal

strip of gold metal

gold(III) chloride solution

zinc(II) chloride solution

sodium chloride salt bridge

a length of copper wire

light bulb

d. Student 4

1 large beaker

strip of cadmium metal

strip of copper metal

copper(II) chloride solution

cadmium chloride solution

sodium chloride solution

a porous membrane

a length of copper wire

light bulb

Explanation / Answer

Student 1 will not light up the bulb as he has taken sodium nitrate instead of silver nitrate.

There is no Ag+ ion available for reduction. Ag has to be reduced as its reduction

potential is higher than Al.
