ABSTRACT
The organics are chemicals containing carbon, forming carbon-carbon covalent bonds and / or carbon-hydrogen.In many cases also contain oxygen and nitrogen, sulfur, phosphorus, boron, halogens and other elements.
The laboratory determined the melting point of sulfur and salicylic acid as the first part,this procedure is used for determining the point where the solid melts. Introduced a small amount of powdered solid sealed in a capillary at one end to the bottom right compacting the sealed end. Thecapillary is fastened to the thermometer with wire, ensuring that the sample is at the same height of the thermometer bulb. Both are immersed in an oil bath without getting it in the capillary. Heatingstarts taking care that the temperature does not rise very quickly, there is the point where the solid melts and the temperature is reported.
Then placed in several test tubes 1ml of liquidsubstances, is then added to each tube a small amount of solid to come into contact thereby obtaining solid and liquid which melted and some others do not.
With PH indicator paper recognized the PH adequatenumber of substances proposed by the teacher.
KEY WORDS
Naphthalene, petroleum ether.
RESUMEN
Los compuestos orgánicos son sustancias químicas que contienen carbono, formando enlaces covalentescarbono-carbono y/o carbono-hidrogeno. En muchos casos contienen oxigeno y también nitrógeno, azufre, fosforo, boro, halógenos y otros elementos.
En el laboratorio se determino el punto de fusión delacido salicílico y el azufre como primera parte, Este procedimiento se utiliza para la determinación del punto en el que un sólido se funde. Se introdujo una pequeña cantidad del sólido pulverizadoen un capilar sellado por un extremo, Compactándolo bien hasta el fondo del extremo sellado. El capilar se Sujeta al termómetro con hilo, asegurándose que la muestra quede a la Misma altura del bulbo...
