In Brazilian Portuguese, 'base primária' is a technical term used primarily in chemistry education and professional contexts. In sports, baseball terminology is less prevalent in Brazil than in the United States, as baseball is not the primary sport, though the terminology is understood among sports enthusiasts. The term is more commonly encountered in academic settings when discussing chemical properties and reactions.
