The solution is strongly alkaline because ethoxide ions are … WitrynaIt is analogous to sodium hydroxide, and is a strong base. Preparation. One laboratory synthesis entails treatment of sodium ethoxide (NaOEt) with hydrogen sulfide: NaOCH 2 CH 3 + H 2 S → NaSH + CH 3 CH 2 OH. An alternative method involves reaction of sodium with hydrogen sulfide. Applications. Thousands of tons of NaSH are …
