Write formulas for the compounds that form from In and each of the following polyatomic ion: NO−3, SO2−4, PO3−4.
(Assume In charge is 3+.)
InNo9, InSO6, AND InP4 is wrong
To determine the correct formulas for the compounds formed between In (indium) and each of the polyatomic ions, we need to consider the charges and balance them.
1. In and NO3-:
Indium has a charge of 3+ (In3+), and the nitrate ion (NO3-) has a charge of 1-. To balance the charges, we need three nitrate ions for every one indium ion. Therefore, the formula for the compound formed is In(NO3)3.
2. In and SO42-:
Indium again has a charge of 3+ (In3+), and the sulfate ion (SO42-) has a charge of 2-. To balance the charges, we need two sulfate ions for every one indium ion. Thus, the formula for the compound will be In2(SO4)3.
3. In and PO34-:
Indium retains its charge of 3+ (In3+), and the phosphite ion (PO34-) has a charge of 3-. The charges are already balanced, so we only need one indium ion for every one phosphite ion. Therefore, the formula for the compound formed is InPO3.
So, the correct formulas for the compounds formed between In and each of the given polyatomic ions are:
- In(NO3)3
- In2(SO4)3
- InPO3
