我想問下 metal + alkaline 會唔會有reaction

Most metals do not react with strong alkali.

Only a few metals can react with strong alkali to give hydrogen gas, and such metals are known as amphoteric metals. Aluminium and zinc are two common examples of amphoteric metals.

The equation for the reaction of aluminium with sodium hydroxide solution:
2Al(s) + 2OH-(aq) + 6H2O(l) → 2[Al(OH)4]-(aq) + 3H2(g)

The equation for the reaction of zin with potassium hydroxide solution:
Zn(s) + 2OH-(aq) + 2H2O(l) → 2[Zn(OH)4]2-(aq) + H2(g)
=

咁就要睇下咩alkaline啦
你所舉既例子就唔得
但如果係FeOH , PbOH etc.既話就得
佢地既會係置換反應(亦可叫氧化還原作用)
只要alkaline入面既金屬雜子既活潑性比你放既金屬低
就會有置換反應,,即係reaction
