What is the charge of a sulfate ion?
-2
Sulfate is a polyatomic ion with 1 sulfur (6 valence electrons), 4 oxygens (4 x 6 valence electrons = 24 e-) and a charge of -2 (2 valence electrons).
How many charges are in sulfate?
Sulfate has a 2− charge. In order to understand why this polyatomic ion has a charge, the formal charge of one of the resonance structures can be observed. In the image below, the oxygen atom labeled 1 has 6 valence electrons.
How do you calculate moles of ions?
Number of mol is calculated by ratio of given mass to the molar mass. After calculating the number of moles, the number of ions will be equal to the product of the number of moles and Avogadro’s number.
Why is the charge of sulphate 2?
Sulfur can have either a partial positive charge or a partial negative charge. Hydrogen Sulfide = H2S, which can break down to H+ and HS- [sort of like water]. We would need 32 valence electrons for 4 full outer shells(8×4) but only have 30. Thus the charge is 2- for the ion.
What is the overall charge on a phosphate ion?
3-
Luckily, we know the charge on the anion: phosphate is a polyatomic ion that always has a charge of 3-.
What is the charge of S in the ion SO42?
Sulfur is at +6 oxidation state in SO42-. Also, sulfate ion has a -2 charge.
How many ions are in a mole?
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).

Why does phosphate have a charge of 3?
So for the whole PO4 group to be stable, the P loses 5 electrons and the 4 Os gain 2 electrons each (total 8 electrons gained). The 5 from the P and another 3 from some other atoms (like hydrogen for example). So the PO4 has an overall 3 electrons more than the protons it has. So it is negatively charged.
What is the total charge on the sulphate anion?
The oxygen atoms that are singly bonded to the sulphur atom each hold a negative charge of magnitude -1. Therefore, the total charge on the sulphate anion is -2. The charge on the magnesium cation has a magnitude of +2.
What is the molarity of sulfate ions in sodium sulfate solution?
In solution, sodium sulfate dissociates according to the following equation: Therefore, 1mol of N a2SO4 will give 1mol of SO2− 4 and thus, the molarity of sulfate ions will be equal to that of the sodium sulfate. M SO2− 4 = 0.150M
