O QUE SIGNIFICA LITMUS TEST EM INGLÊS
Litmus
Litmus é uma mistura solúvel em água de diferentes corantes extraídos de líquenes, especialmente Roccella tinctoria. Muitas vezes, é absorvido em papel de filtro para produzir uma das formas mais antigas de indicador de pH, usado para testar materiais para a acidez. O papel azul de tornassol torna-se vermelho sob condições ácidas e o papel de tornassol vermelho fica azul em condições básicas, com a mudança de cor sobre a faixa de pH 4,5-8,3 a 25 ° C. O papel de tornassol neutro é roxo. Litmus também pode ser preparado como uma solução aquosa que funciona de forma semelhante. Em condições ácidas, a solução é vermelha e, em condições básicas, a solução é azul. A mistura de lâmina tem o número CAS 1393-92-6 e contém 10 a 15 corantes diferentes. A maioria dos componentes químicos do torniquete é susceptível de ser o mesmo que os da mistura relacionada conhecida como orceína, mas em diferentes proporções. Em contraste com a orceína, o constituinte principal do torniquete tem peso molecular médio de 3300. Os indicadores de base de ácido no litso devem suas propriedades a um cromóforo de 7-hidroxifenoxazona. Algumas frações de tornasão receberam nomes específicos, incluindo eritrolitrina, azolitmina, espaniolitmina, leucoorceína e leucazolitmina.
