Question

work out the chemical formula for sodium sulphite using cross method

​

Answer 1

Answer:

Explanation:

Formula of sodium sulfate is Na2SO4. It is an ionic compound and consists of 2 sodium ions and 1 sulfate ionFormula of sodium sulfate is Na2SO4. It is an ionic compound and consists of 2 sodium ions and 1 sulfate ion. Sodium is a cation while sulfate is an anion. Sodium has +1 charge and sulfate has -2 charge on it.

According to criss cross rule:

                                    Na      SO4

                                     +1         -2

Now according to the rule exchange their charges. After cross over charges 2 will be assigned to Na and 1 will be assigned to SO4.

The final product will be Na2SO4.
