Marcela Rodriguez Ricardo Sarabia January 16‚ 2013 Mariana Mendoza Alvaro Puccini Maria Quin Solubility Lab Purpose: The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated‚ diluted‚ supersaturated‚ and saturated substances and how can they be identified. The hypothesis

our findings‚ we were able to determine the mass of the determined and the percent recovery of matter. The outcome of the experiment was that we made the correct calculations which gave us the confidence to know how to do an analysis of mixture. Introduction A mixture is a material that is not uniform in composition‚ and it is a combination of two or more substances in which each substance retains its own chemical identity. Mixtures are characterized by how each of the substances in the mixture retains

The Effect of Different Molar Mass on the Diffusion on Substances Lunar-maius A. Gaerlan Group 2 Sec. X – 9l August 15‚ 2012 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using agar-water gel test. The agar-water gel set up was composed of a petri dish of agar-water gel containing three wells. Drops of potassium permanganate (KMnO4)‚ potassium dichromate (K2Cr2O7) and methylene blue(C16H18N3SCl) were simultaneously introduced to each well. Methylene blue
