      Sim. Ele multiplica, mas fica como índice.

    Bom dia,
    eu classifico Hidrogenossais/Sais Ácidos aqueles que apresentam H+ na fórmula(por terem sofrido neutralização parcial), ex: NaHCO3 - bicarbonato de sódio ; ou aqueles que formam uma solução ácida em contato com a água, ex: MgSO4- sulfato de magnésio?

    Quando devo colocar parêntese na fórmula?

    •  5 ปีที่แล้ว +2

      Sempre que a estrutura repeti a estrutura. Tipo tem na fórmula OH duas vezes. Então você coloca (OH)2.

    • @soniaxavier159
      @soniaxavier159 5 ปีที่แล้ว +1

      exemplo: (OH)2. você coloca para dizer que tem duas moléculas de hidroxila, pois se vc colocar O2 H2 não vai ser mais hidroxila pois é sempre OH
