To determine the formula and charge of the oxoanion in each compound, we need to understand the names of the compounds and the valences of the elements involved.
1. Potassium sulfite:
To find the formula and charge of the oxoanion in potassium sulfite, we first need to identify the elements present. In this case, we have sulfur (S) and oxygen (O).
The charge on potassium ions is always +1 (K+). So, to neutralize the overall charge, the oxoanion should have a total charge of -1.
We determine the formula of the sulfite oxoanion by balancing the charges of sulfur and oxygen. We have one potassium ion (K+) with a charge of +1. Hence, the sulfite oxoanion (SO3) must have a charge of -2 to give an overall charge of zero for the compound.
Therefore, the formula and charge of the oxoanion in potassium sulfite is SO3^2-.
2. Sodium perchlorate:
Similarly, we identify the elements in sodium perchlorate as sodium (Na) and chlorine (Cl).
The charge on sodium ions is always +1 (Na+). So, to neutralize the overall charge, the oxoanion should have a total charge of -1.
To find the formula of the perchlorate oxoanion, we balance the charges. We have one sodium ion (Na+) with a charge of +1. Hence, the perchlorate oxoanion (ClO4) must have a charge of -1 to give an overall charge of zero for the compound.
Therefore, the formula and charge of the oxoanion in sodium perchlorate is ClO4^1-.
3. Lithium phosphite:
In lithium phosphite, we have lithium (Li) and phosphorus (P).
The charge on lithium ions is always +1 (Li+). So, to neutralize the overall charge, the oxoanion should have a total charge of -1.
To determine the formula of the phosphite oxoanion, we balance the charges. We have one lithium ion (Li+) with a charge of +1. Therefore, the phosphite oxoanion (PO3) must have a charge of -2 to give an overall charge of zero.
Therefore, the formula and charge of the oxoanion in lithium phosphite is PO3^2-.
4. Magnesium hypochlorite:
Lastly, in magnesium hypochlorite, we have magnesium (Mg) and chlorine (Cl).
The charge on magnesium ions is always +2 (Mg2+). So, to neutralize the overall charge, the oxoanion should have a total charge of -2.
To find the formula of the hypochlorite oxoanion, we balance the charges. We have one magnesium ion (Mg2+) with a charge of +2. Therefore, the hypochlorite oxoanion (ClO) must have a charge of -1 to give an overall charge of zero.
Therefore, the formula and charge of the oxoanion in magnesium hypochlorite is ClO^-1.
