QUÉ SIGNIFICA SILICIC ACID EN INGLÉS
Ácido silícico
Ácido silícico / sɪlɪsɪk ˌæsɪd / es un compuesto químico. Es un silanol. Ácido silícico es el nombre general para una familia de compuestos químicos que contienen el elemento de silicio unido a grupos de óxidos e hidroxilo. Esta familia de compuestos tiene la fórmula general n. Se han identificado algunos ácidos silícicos simples, pero sólo en solución acuosa muy diluida, tal como ácido metasilícico, ácido ortosilícico, ácido disilícico y ácido pirosilícico; Sin embargo, en el estado sólido, éstas probablemente se condensan para formar ácidos silícicos poliméricos de estructura compleja.
definición de silicic acid en el diccionario inglés
La definición de ácido silícico en el diccionario es una sustancia gelatinosa blanca obtenida mediante la adición de un ácido a una solución de silicato de sodio. Tiene una composición mal definida y se considera mejor como sílice hidratada, SiO2. nH2O.
