evidence that help conclude that the mystery mixture ( number 8) is composed of citric acid and sodium bicarbonate the same as mixture six . At first when just observing the dry mixtures‚ it was hard to determine which ones were identical to the mystery mixture. In order to figure out which substances combined to make the mystery mixture‚ another process we followed was adding water to the substances and observing the reaction. Adding water to the mixtures resulted in a chemical reaction. The materials

Natural dyes Natural dyes are dyes or colorants derived from plants‚ invertebrates‚ or minerals. The majority of natural dyes are vegetable dyes from plant sources – roots‚ berries‚bark‚ leaves‚ and wood — and other organic sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the Neolithicperiod. In China‚ dyeing with plants‚ barks and insects has been traced back more than 5‚000 years.[1] The essential process of dyeing changed little over time

Separating the components of a Ternary Mixture Introduction Mixtures are usually content of two or more substances. There are two kind of mixtures‚ Homogeneous and heterogeneous mixtures. For Homogeneous mixture we cannot see the individual particles of the components‚ a good example of that will be air‚ cola drink‚ and rubbing alcohol. And for heterogeneous mixture we can see the individual particles of the components‚ a good example of that will be rocks and soil. There are a variety of methods
