The word "sodium" comes from the Latin word "sodanum", which was derived from the Arabic word "suda", meaning headache. "Sodanum" refers to a headache remedy, likely because sodium carbonate, a compound used in headache medication, was originally derived from it. "Hydroxide" is a chemical term derived from the Greek words "hydro" meaning water and "oxys" meaning sharp or acid. Hence, "sodium hydroxide" refers to a compound composed of sodium and hydroxyl (OH-) ions.
