Question

Give an example reaction for the following:

Base + amphoteric metal --> complex ion + hydrogen gas

Base + ammonium salt --> ammonia gas

Answer 1

Base = NaOH
Amphoteric metal : Alluminium

Al + 3NaOH -> ... ?

Answer 2

Can you tell me what will be formed here?

Answer 3

Al + NaOH = ?

Answer 4

Na[Al(OH)4] + H2 ??

Answer 5

No .. dear Al is less reactive reactive then Na hence it will not be able to displace Na from NaOH ..

Answer 6

that's why i asked you this

Answer 7

Oh... so I'm not quite sure what the complex ion would be :S

Answer 8

Does it involve [Al(OH)4]-1 ?

Answer 9

First of all the valency of Al is 3+ and OH is 1-

so \[\large{Al_1(OH)_3=Al(OH)_3}\]
