The chemical formula of iron ii phosphate is Fe3(PO4)2. This compound is a naturally occurring salt of phosphoric acid that can be formed by the reaction of ferrous hydroxide and phosphoric acid. It can be used in water treatment and molluscicides.
The oxidation state of iron (II) is +3 while the oxidation state of phosphate is -3. How do you find out the correct chemical formula for this compound?
First of all, you need to know what the Roman numerals mean. They represent the oxidation states of the elements in a compound, and are the most important part of a formula.
Next, you need to figure out the atomic weight of the element in question. The atomic weight of iron is 64.0, while the atomic weight of phosphate is 32.4. The atomic weight of the compound is then calculated by multiplying the atomic weights of each element in the formula.
Lastly, you need to calculate the number of atoms in each molecule of the compound. This can be done by using a table. The simplest way to do this is by following the Hill system, which gives you a number of formula units for each molecule or ion in the chemical equation.
The chemical formula for the most obvious molecule is actually a double displacement reaction where Fe and Na displace their places to form iron (II) phosphate and sodium chloride. This double displacement reaction is one of the most interesting and exciting chemical reactions in the science field.
