Sodium carbonate has sodium, carbon and oxygen in it, and the molecular formula is NaCO. Sodium hydroxide is consists of the elements sodium, oxygen and hydrogen and it has the molecular formula NaOH.
One of the common features of both these compounds are being alkali in aqueous medium.

Soda is an ambiguous term that could mean any of several different things. It's been used to refer to sodium carbonate Na2CO3, sodium hydrogen carbonate NaHCO3, sodium hydroxide NaOH, and sodium oxide Na2O. It also is used to mean carbonated beverages, which are mixtures, not compounds, and therefore don't have molecular formulae.
Ionic
Water reacts with carbon dioxide in the air to form small amounts of carbonic acid. In a sodium hydroxide solution, this reacts again to form sodium carbonate.
The scientific name for caustic soda is sodium hydroxide with the chemical formula NaOH.
Soda is sodium hydroxide (NaOH) or sodium carbonate (Na2CO3).
Examples: sodium chloride, sodium carbonate, sodium hydrogen carbonate, sodium hydroxide, sodium sulfide, sodium acetate, sodium bromide, borax, etc.
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
sodium hydroxide, quicklime or Calcium Oxide, Slaked lime or calcium hydroxide, Potassium Hydroxide or caustic potash or lye. Sodium Carbonate; potassium carbonate, rubidium oxide, ammonia etc.
NaHCO3 + CaCO3 = CO2 + CaCO3 + NaOH
