   Note

   In the laboratory the base behind the word is a chemical one. In water at room temperature, a basic solution sits above 7 on the pH scale because the base takes up hydrogen ions. When a chemist calls a solution strongly basic, that describes its chemistry and does not mean it is simple. In mixed technical writing, context has to keep it apart from the everyday "elementary" meaning. Source
