El objetivo ha sido determinar el contenido de \u00e1cido ac\u00e9tico de un vinagre , procediendo a valorarlo.<br>Para ello medimos 10,0 mL del vinagre, lo echamos en un matraz erlenmeyer, diluimos hasta unos 25 -30 mL (no<br>importa el volumen final) y a\u00f1adimos un par de gotas defenolftale\u00edna como indicador. La fenolftale\u00edna es incolora<br>por debajo de pH 8,2, virando a un color violeta intenso por encima de pH 10,0.<br>La bureta se llena con disoluci\u00f3n de NaOH de concentraci\u00f3n conocida (1,0 M en nuestro caso).<br>Una vez listo el montaje comenzamos a valorar vertiendo lentamente la disoluci\u00f3n de hidr\u00f3xido de sodio sobre el<br>vinagre, al tiempo que se agita el matraz. El vertido se contin\u00faa hasta que el indicador vire al color violeta. Cerramos entonces la bureta y medimos el volumen de disoluci\u00f3n vertida. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"768\"
