Question

a 1.0mol/l solution of ni(no3)2(aq) could be stored in a container made of
a. tin
b. chromium
c. zinc
d. iron

Explanation:

Based on the activity series of metals, tin is less reactive than nickel. So a tin container can store nickel - nitrate solution without a chemical reaction occurring between them. Metals more reactive than nickel (like iron, zinc, and chromium) would displace nickel from its nitrate solution.

Answer:

a. tin
