A acidez gástrica excessiva constitui um problema de saúde frequente, geralmente tratado com a administração de antiácidos. Entre estes, o hidróxido de magnésio [Mg(OH)₂] é um composto básico amplamente reconhecido pela sua capacidade de neutralizar rapidamente a acidez gástrica. No entanto, um conhecimento aprofundado das suas propriedades físico-químicas, associado a uma síntese controlada em laboratório, continua a ser essencial para garantir a sua eficácia terapêutica e a segurança da sua utilização. A questão central deste trabalho reside na necessidade de produzir um hidróxido de magnésio puro e eficaz, suscetível de constituir uma alternativa local aos medicamentos importados. O objetivo principal deste estudo é, portanto, a síntese do Mg(OH)₂, a sua caracterização através de diferentes técnicas analíticas, bem como a avaliação da sua atividade antiácida, a fim de avaliar o seu desempenho. A nível experimental, o hidróxido de magnésio foi obtido por reação de precipitação a partir de uma solução de cloreto de magnésio e hidróxido de sódio (NaOH).
