# Ionic Formula Calculator

Top
Ionic compounds comprise positively charged ions (cations) and negatively charged ions (anions) which are held by Ionic bond. Ionic compound has zero charge, therefore, the sum of the positive charge should be equal to the sum of the negative charge. Plug in the Ionic compounds in words into the Ionic formula calculator to determine the ionic formula of the given Ionic compound.

## Steps

Step 1 : Write down the cation and anion of the given ionic compound.

Step 2 : Put the cation and anion next to each other and cross the charges.

Step 3 : Combine both the anion and cation without its charge to get the formula of ionic compound.

## Problems

Given below are some of the problems based on ionic formula.

### Solved Examples

Question 1: Find the ionic formula of Sodium carbonate.

Solution:

Step 1 : Given : Sodium Carbonate
Cation : Sodium ion with +1 charge = $Na^{+}$
Anion : Carbonate ion with -2 charge = $CO_{3}^{2-}$

Step 2 : Cross the charges :

Step 3 : $Na_{2} (CO_{3})_{1}$ = $Na_{2}CO_{3}$

Therefore, the formula for Sodium carbonate is $Na_{2}CO_{3}$.

Question 2: Find the ionic formula of Magnesium Chloride.

Solution:

Step 1 : Given : Magnesium Chloride
Cation : Magnesium ion with +2 charge = $Mg^{2+}$
Anion : Chloride ion with -1 charge = $Cl^{-}$

Step 2 : Cross the charges :

Step 3 : $Mg_{1}Cl_{2}$ = $MgCl_{2}$

Therefore, the formula for Magnesium Chloride is $MgCl_{2}$.
