What is the chemical formula corresponding to caustic soda?

Explanation:
Caustic soda is sodium hydroxide, a strong base used in many industrial and cleaning applications. Its formula NaOH reflects one sodium ion bonded to one hydroxide ion, which together form the characteristic caustic behavior in water. The other formulas correspond to different substances: NaCl is table salt, Na2CO3 is sodium carbonate (soda ash), and NaHCO3 is sodium bicarbonate (baking soda). The name caustic soda specifically refers to the hydroxide compound, not those other salts.
