Answer:
potassium and sodium
Step-by-step explanation:
There are many metals that can react with aluminium nitrate in a displacement reaction. these metals are higher than aluminium in the electrochemical series of elements where metals are arranged based on their reactivity and therefore tend to displace aluminium in any chemical reaction. However the most reactive of these metals are potassium(K) and sodium(Na). Others are calcium(Ca), magnesium(Mg), lithium(Li), strontium (Sr).
