Answer :
The name of compound
is, potassium iodide.
The name of compound
is, iron (III) oxide.
The name of compound
is, ammonium phosphate.
Explanation :
Ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.
The rules of ionic compounds is given by:
- Positive ion is written first.
- The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
- In case of transition metals, the oxidation state are written in roman numerals in bracket in-front of positive ions.
(1) The given compound
is an ionic compound. It is made up of two different ions which are potassium ion
and iodide ion
.
So, the name of
is, potassium iodide.
(2) The given compound
is an ionic compound. It is made up of two different ions which are iron ion
and oxide ion
. In this an oxidation state of iron is (+3).
So, the name of
is, iron (III) oxide.
(3) The given compound
is an ionic compound. It is made up of two different ions which are ammonium ion
and phosphate ion
.
So, the name of
is, ammonium phosphate.
