Write the formulas for the four ionic compounds that can be made by combining each of the cations Na+ and Ba2+ with the anions CO32- and l–. Name each of the compounds.

Interpretation Introduction

Interpretation: The names of ionic compounds formed by cations Na+ and Ba2+ with the given anions CO32 and I are needed to be determined.

Concept introduction:

Ionic compounds are formed by electrostatic attraction between ions such as mono atomic ions and polyatomic ions; in which positively charged ions is known as cations and negatively charged ions are known as anions.

The sum of charges of ions present in an ionic compound is equals to net charge of the compound. The net charge of the ionic compound must be zero, because it should be balanced.

Naming of ions:

Positive ions (cations) are named as metal name plus cation, example: aluminum cation.

But, for the transition metals the ionic charge also included by roman numerals with the naming of compound. The polyatomic cation NH4+ is named as ammonium cation.

Negative ions (anions) are named by adding ‘ide’ to the stem of the nonmetal element from which the anion is formed, example: chloride, bromide, etc. in case of poly anions, the oxoanions series is named by checking the number of oxygen atom is present in it. If the oxoanion is having greater number of oxygen, then suffix will be ‘ate’. If the number of oxygen atom is less, then the suffix will be ‘ite’. And if the oxoanio is having more than elements, then prefix will be added as ‘per’ with suffix ‘ate’ ions and ‘hypo’ with suffix ‘ite’ of the oxoanions.

Explanation

Ionic compounds are formed by electrostatic attraction between ions such as monoatomic ions and polyatomic ions; in which positively charged ions is known as cations and negatively charged ions are known as anions.

Therefore,

Na+ with CO32 and I forms ionic compounds.

The sum of charges of ions present in an ionic compound is equals to net charge of the compound. The net charge of the ionic compound must be zero, because it should be balanced.

So, two Na+ ions are required to balance +2 charge of CO32.  And one Na+ enough to balance I ion.

Hence,

The ionic compound formed by Na+ with anions CO32 and I are Na2CO3 and NaI
