Formulações

Aplicações:

Usa-se como antiácido, para tratar a acidez do estômago porque ele tem o poder de neutralizar os excessos do ácido clorídrico do suco gástrico, devido ao facto de ser uma substância ligeiramente alcalina (ph=9). Em algumas formulações farmacêuticas, é misturado aos ácidos cítrico e tartárico, ambos sólidos.^[1]

Devido à capacidade do bicarbonato de sódio libertar dióxido de carbono gasoso (CO₂), também é muito usado nas receitas de culinária como agente levedante ("fermentos químicos"), para ser utilizado no crescimento das massas de pães, bolos e biscoitos durante o cozimento no forno, em especial quando misturado ao ácido tartárico, e na produção de bebidas gasosas (refrigerantes).

Além do uso farmacêutico e culinário, o bicarbonato de sódio também é um ótimo auxiliar na limpeza de ambientes e de roupas. O produto tem ação anti-mancha, anti-mofo e elimina o mau cheiro.

Outras utilizações do bicarbonato de sódio são como reagente de laboratório, na eletrodeposição de ouro e platina, em curtumes, no tratamento da lã e da seda, na nutrição de animais, na cerâmica, para a preservação da manteiga e da madeira e é um dos componentes dos talcos e desodorantes. A forma anidra do composto usa-se para absorver umidade e odores.

É utilizado na fabricação de extintores de incêndio com produção de espuma. No interior destes extintores encontram-se NaHCO₃ sólido mantido em compartimento separado de uma solução de ácido sulfúrico (H₂SO₄). Quando estes extintores são virados, o que causa seu acionamento, o NaHCO₃ e o H₂SO₄ se misturam e reagem, com liberação de CO₂, propiciando pressão dentro do vaso, que causa sua ejeção e produzindo a espuma. Esses extintores são inadequados para uso em chamas em equipamentos e instalações elétricas, pois seu meio aquoso e salino conduz corrente elétrica, causando curtos-circuitos.
