(^these are symbolize subscripts)
1. CoCl^3
2. CrF^6
3. AgBr
4. Fe^20^3
5. CrF^3
6. TiCl^4
To name these compounds, you need to identify the elements involved and their respective oxidation states. Here's how you can figure it out:
1. CoCl3
The compound consists of cobalt (Co) and chlorine (Cl).
Using the rules of naming binary compounds, you know that cobalt has multiple oxidation states. The oxidation state of chlorine is typically -1 in binary compounds.
To balance the charges in the compound, you need three chlorine ions for every cobalt ion. Therefore, the compound is called cobalt(III) chloride.
2. CrF6
The compound consists of chromium (Cr) and fluorine (F).
Similar to cobalt, chromium also has multiple oxidation states. The oxidation state of fluorine is -1.
To balance the charges, you need six fluoride ions for every chromium ion. Therefore, the compound is called chromium(VI) fluoride.
3. AgBr
The compound consists of silver (Ag) and bromine (Br).
Silver is known to have a fixed oxidation state of +1. Bromine has an oxidation state of -1.
Since both elements have simple charges, no subscripts are required. The compound is called silver bromide.
4. Fe2(CO3)3
This compound consists of iron (Fe) and carbonate ions (CO3).
To determine the oxidation state of iron, you need to take into account the charge of the carbonate ion. Each carbonate ion has a charge of -2.
The compound suggests that there are three carbonate ions present. To balance the charges, you would need two iron(III) ions for every three carbonate ions.
Therefore, the compound is called iron(III) carbonate.
5. CrF3
The compound consists of chromium (Cr) and fluorine (F).
Similar to before, chromium has multiple oxidation states, while fluorine has an oxidation state of -1.
To balance the charges, you need three fluoride ions for every chromium ion. Therefore, the compound is called chromium(III) fluoride.
6. TiCl4
The compound consists of titanium (Ti) and chlorine (Cl).
Titanium can have multiple oxidation states, and chlorine has an oxidation state of -1.
To balance the charges, you need four chloride ions for every titanium ion. Therefore, the compound is called titanium(IV) chloride.
