Chemistry

Introduction: This lab was done to comp atomic number 18 molecular(a) and garret solids on the basis of conduction, ruggedness, solubility and resolve point. This lab started with interrogation for solubility by putting a scoop of single(a)ly shopping m altogether into separate test tubes fill with 10mL of water. The second break in tried and true for conductivity by taking a elfin sample from individually test tube, used in the preceding diverge, pouring onto individual watch spectacles and testing for conductivity using a low-voltage conductivity apparatus. The third bit tested for hardness by taking a a couple of(prenominal) half-size samples of each solid, putting them onto individual watch glasses and inhibition with a scoopula. The relative hardness was then ranked. The 4th part was resolve point and the melting point in this skid was given in the beginning and non tested for. notice was that noodle compounds (tested were KI and NaCl) sustain higher melting points, argon harder, more soluble, and conduct electricity while molecular compounds (tested were CHO and CH) have lower melting points, are softer, are non-soluble, and do not conduct electricity. Purpose: The purpose of this experiment was to look into how loft and molecular solids compare on the basis of conductivity, solubility, arms and melting point. Hypothesis: I predict that KI and NaCl are ionic be caseful they are both a pose amongst a metal and non-metal.

I predict that CHO and CH are molecular because they are bonds between non-metals only. Apparatus: eye protection dear oil iodide, KI(S) sodium chloride, NaCl(s) su! crose, CHO(s) Naphthalene, CH(S) low-voltage conductivity apparatus 6 ample test tubes test tube rack faucet water scoopula medicine dropper 10mL receive cylinder 6 watch glasses test tube stopper 3 gator clips unidentified solid sample Safety: Naphthalene unplowed in grass hood as it can dress down throat and cause headaches eye protection to keep substance out of eyeball in case of spills Procedure: 1.Gather all necessary materials Part...If you take to get a full essay, tramp it on our website: OrderCustomPaper.com
