Aluminum displaces cobalt from a 0.2 M solution of cobalt(II) perchlorate. Cobalt does not displace chromium from a solution of 0.2 M chromium (III) nitrate. Aluminum metal does not displace calcium from a 0.2M solution of calcium nitrate. Aluminum metal displaces chromium from a solution of 0.2 M chromium (III) nitrate. Write an activity series, most active to least active, based on this data.
