An element which lies between Al and Pb in the reactivity series would be expected to _______
1. react with Al when heated
2. liberate H2 from HCl acid
3. displace Na from aq. solution of Na salt
4. form a hydroxide which dissolves in water
It's either 2 or 4...i think it's 2 but not sure. Do give me your opinion on this question.Thanks
Should be 2.
4 is wrong as it is mostly only Group 1 metal hydroxides that are soluble in water.
