Aluminum sulfate is formed when an aluminum cation that has a 3+ charge combines with a sulfate ion that has a 2- charge. write the formula for the compound aluminum sulfate. font sizes

Answer : The formula for the compound aluminum sulfate is

Explanation :

For formation of a neutral ionic compound, the charges on cation and anion must be balanced.

The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non-metals.

In the given question, the aluminum metal forms an ionic compound with polyatomic anion (sulfate) .

Here, aluminum is having an oxidation state of +3 called as cation and sulfate is an anion with oxidation state of -2. The charges are not balanced. So, the charges are balanced by the cris-cross method. Thus, the compound formed will be,

Hence, the formula for the compound aluminum sulfate is

it's filtration, but this is an assumption so my apologies if i got this
