Lab 1: Classifying Chemical Reactions
We used 7 test tubes to perform 7 different reactions. We watched a magnesium metal strip burn, combined hydrochloric acid & magnesium powder to produce heat, combined hydrogen peroxide & manganese oxide to reignite a glowing splint, combined calcium carbonate & hydrochloric acid which caused the flame to go out, combined copper chloride solution & zinc to change the color of the zinc, combined copper chloride solution & sodium phosphate to produce a light blue liquid, and combined sodium hydroxide & phenolphthalein & hydrochloric acid to produce a clear liquid. We knew if a reaction took place if the reactants were altered and what was observed while they were being changed. The purpose of this lab was to show the relation of reactants and products in an equation. It also showed reaction types such as synthesis, single replacement, double replacement, decomposition, and combustion.
Lab 2: Iron-Copper Tango
To begin this lab we: took 13 grams of copper (II) sulfate pentahydrate, combined it with 150 ml of distilled water to dissolve sulfate crystals, stirred it with a rod, while stirring added 2 grams of steel wool and stirred for 7 minutes, took filter paper and folded it into a funnel, poured the liquid into the funnel to filter out the solution to get the steel wool, placed the filter paper in the drying oven, and waited a day only to weigh the dried filter paper. The purpose of this lab was to calculate the mass and number of moles of copper produced and the number of moles of iron that reacted. Also to determine the molar relationship between iron and copper. We discovered that the molar ratio of iron and copper was 1:1. This lab was done to further our knowledge of stoichiometry, to understand mole ratios, and to refresh our memories on the wonderful t-charts.
