Answer 2

Answer:

the valency of zincate ion is 2 !!!!

Sodium Zincate is formed by Sodium cation (Na+) and Zincate anion (ZnO2-2) thus, giving rise to the chemical formula of Na2Zno2. Here, zincate anion has valency 2........

But sodium aluminate is formed by sodium cation (Na+) and aluminate anion (AIO-). Here, aluminate anion has valency ......We get the formulae by the criss-crossing of the valencies.......
