Individual Solid Nonmetal analysisMany chemicals come in the form of powders or crystals. At first quick glance, itmay look like they all look rather similar. But a closer look will show you that there aresome major differences right off. We are going to look at 13 different solid nonmetalsubstances. We will learn how to identify them individually and then we will look at howto identify some of them when they are mixed together. As with the liquids and themetals, the identification will be on the basis of how the materials look, smell, their pHwhen mixed with water and if/how they dissolve or react with water, acid and iodine.The first thing you need to observe is whether the solid is a powder, crystal, orgranule. This will be done by looking at the substance with a magnifying glass. As withthe liquids and metals, the ID material will be given to you in both a table and decisionchart. You will be expected to record your own observations on the individual solidnonmetals. We will be using a wooden splint to take small amounts of the substances andputting in the wells of a "spot plate". While they are in the spot plate, you can test themfor how they react with water, acid, iodine, etc. But of course you will not want to addmore than one reagent to the solid at a time. Therefore you will need to keep cleaning thespot plate between each set of trials. You have a jar at your desk that you should use yourwash bottle to wash the residue in the spot plate after each set of tests into.Substance Shape & Size pH Solubility in Reaction to Reaction to I 2 Otherwater HClObservationsAlka-Seltzer Powder ~6 Fizzes Fizzes Stains pale CrumblesyellowBaking Soda Powder ~8 Soluble Fizzes Stains paleCalciumCarbonatePowder ~6 Insoluble seeendFizzesyellowStains paleyellowMay appear todissolve, butsettlesCornstarch Powder ~8 Soluble-smooth No Reaction Turns blueFlour Powder ~6 Soluble-lumpy No Reaction Turns blueGelatin Crystal ~6 Soluble-jellylikeNo reaction Stains paleyellowGypsum Powder ~6 Solublew/bubblesNo reaction Stains paleyellowSalt Uniform cubes ~7 Soluble No Reaction Stains paleyellowSand Irregular shape ~6 Insoluble No Reaction Stains paleyellowSodium Irregular ~8 Soluble No Reaction Stains paleAcetate ShapeyellowSugar Irregular Size ~7 Soluble No Reaction Stains paleyellowVitamin C Irregular Size ~2 Soluble No Reaction Turns I 2 clear Crumbles-YellowishYeast Granular ~7 Soluble butdelayNo Reaction Stains paleyellowPale YellowishcastWill not crumbleCrystals almostclearTarnish cloudywater

Or another way to look at the problem is with a decision chart. For nonmetal solids thechart would look like this:YesFizz in YesAlka-SeltzerPowder?H 2 O?NoNoYesSoluble Yes BakingCrystalline?ReactSodain H 2 Ow/HClNoNoCalcium CarbonateYesNoYeastSolublein H 2 O?Turn Bluew/I 2 ?YesYesNoJelly-like?PH~8YesYesNoCornstarchFlourGypsumGelatinSandNoNoPH~8YesSodium AcetateNoTurns I 2 Clear?
