Answer:
K , Na , Ca and Mg
Explanation:
The metals more reactive than Aluminium will react with Aluminium nitrate in a displacement reaction . If we look at the Reactivity series which is ,
K > Na > Ca > Mg > Al > Zn > Fe > Ni > Sb > Pb > H > Cu > Hg > Ag > Au > Pt
Hence the metals more reactive than Al are K , Na , Ca and Mg .
Hence either of the metals from K , Na , Ca and Mg will displace Aluminium from Aluminium nitrate .
Answer:
Anything above aluminium in the reactivity series.
Explanation:
Like potassium, sodium, calcium, etc.
