Question

What is the chemical formula of sodium carbonate in Criss cross method

Answer 1

Answer:

Na2CO3

Explanation:

first consider the cation anion

sodium has the charge Na+

carbonate has CO3^2-

Na CO3

+1 2-

by criss crossing u'll get

Na2CO3

Answer 2

The chemical formula of sodium carbonate in criss cross method is $Na_2CO_3$. Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.  

In sodium carbonate, metal is sodium which can lose one electron to give $Na^+$ and carbonate $CO_3^{2-}$ is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $Na_2CO_3$.

The cations and anions being oppositely charged attract each other through strong coloumbic forces and form an ionic bond.
