What is the main chemical difference between washing soda and baking soda?

Answer and explanation

Correct answer: Washing soda is hydrated sodium carbonate and baking soda is sodium hydrogen carbonate

Washing soda is sodium carbonate decahydrate, Na₂CO₃·10H₂O, whereas baking soda is sodium hydrogen carbonate, NaHCO₃. Thus they differ in both composition and properties: washing soda is used in cleaning and water softening, while baking soda is used in baking and some neutralisation applications. Option A is correct; the other choices assign incorrect names or formulas to these salts.
