✔ 最佳答案
1. Li3N, NaH, CaH22. base is the acceptor of potons, whether it is soluble or not in water
but alkali is just bases that dissolve in water.
3.

1: sodium hydride,calcium hydride, lithium nitride
2:Actually,alkali and base are from the same kind of things
however, base can not dissolve into water and become aqueous solution
while alkali can dissolves and form its aqueous solution.the common example
: NaOH(aq),NH3(aq)andKOH(aq)

你可以當 alkali係base當中既異變
佢地都係base,不過又係soluble
人地就尊稱佢地做alkali了
