Notas de pé
- 1 Ácidos e bases estão comercialmente disponíveis como soluções aquosas. Esta tabela lista as propriedades (densidades e concentrações) de soluções ácidas e básicas comuns. Os valores nominais são fornecidos nos casos em que o fabricante cita uma faixa de concentrações e densidades.
- 2 Esta coluna contém dados específicos de gravidade. No caso desta tabela, a gravidade específica é a razão entre a densidade de uma substância e a densidade da água pura nas mesmas condições. A gravidade específica é frequentemente citada em rótulos comerciais.
- 3 Essa solução às vezes é chamada de “hidróxido de amônio”, embora esse termo não seja quimicamente preciso.
