Question

What is the correct formula of aluminium nitrate?

• A. $A{l}_2(N{O}_3{)}_2$
• B. $Al(NO{)}_3$
• C. $Al(N{O}_3{)}_3$
• D. $A{l}_3(N{O}_3{)}_2$

Answer 1

The correct option is C

$Al(N{O}_3{)}_3$

Correct formula of aluminium nitrate will be $Al(N{O}_3{)}_3$ because valency of aluminium will be +3 while combining capacity for nitrate $N{O}_3$ will be $-1$. So by the criss-cross method, we will get $Al(NO3{)}_3$
