Rule 4
What else can I help you with?
What is the anion of sulfates?
The anion in sulphates is the SO42-.
Is sulfur in sulfates?
Yes, sulfur is present in sulfates. Sulfates are chemical compounds that contain the sulfate ion, which is made up of sulfur and oxygen atoms.
What is the chemical formula for sulfates?
The chemical formula for the sulfate ion is SO42-
What does the word 'sulfate' suggest about a chemical with that in its name?
There are two parts to this question:1) What is a sulfate? -- A sulfate is any molecule that has the ion SO42- in it. That ion is called "sulfate".2) What chemical properties are conferred on sulfates? -- There are no consistent properties across all sulfates, and many more relevant properties derive from the atom paired with the sulfate in an ionic compound. That being said, most sulfates will dissolve easily in water, especially sulfiric acid (H2SO4) which is a strong acid. However, the most commonly used sulfates, like gypsum and barium sulfate are not actually very soluable. Sulfates can often serve as ligands in certain instances.
The SO42- ion is named?
The SO42- ion is named sulfate.
What can be added to a solution of OH- (aq) S2- (aq) and SO42- (aq) ions to precipitate the OH- (aq) ions but not the others?
Add a solution of magnesium chloride; magnesium hydroxide is not soluble in water.
What is the formal charge of the SO42- ion?
The formal charge of the SO42- ion is -2.
From what elements do the sulfates the their names?
Sulfates contain the sulfate ion SO42- the sulf- comes from the fact that sulfur is the central atom in this ion and distinguishes it from other oxygen containing ions. the -ate part of the name shows that the sulfur in the ion is in its highest oxidation state.
What is the formal charge of the sulfate ion (SO42-)?
The formal charge of the sulfate ion (SO42-) is -2.
Why is CaSO4 less soluble in water than NaCl?
The ion-ion bond in CaSO4 is stronger than in NaCl because of the higher charges on the cation and anion. Be careful in making this argument. The ion-dipole forces of Ca2+ -H2O and SO42- - H2O might actually be stronger than that of Na+ -H2O and Cl- -H2O due to the high charges on Ca2+ and SO42- . However the strengths of the ions-dipole interactions do not match (or exceed) the strength of the Ca2+ -SO42- ionic bond.
What ion will most likely form a precipitate when reacted with SO42?
You didn't provide an ion. So since it's a positive most likely a negative ion.
Change in oxidation number in S2O82 TO SO42?
In S2O82-, each S atom has an oxidation number of +5. In SO42-, the oxidation number of S is also +5. There is no change in oxidation number for sulfur when transitioning from S2O82- to SO42-.
