Chemistry

Introduction: This lab was done to comp atomic number 18 molecular(a) and garret solids on the basis of conductivity, badness, solubility and dissolve point. This lab started with interrogation for solubility by putting a scoop of psychely centre into separate test tubes fill up with 10mL of water. The second break in tried and true for conductivity by taking a elfin sample from for each one test tube, used in the preceding diverge, pouring onto individual watch spectacles and testing for conductivity using a low-voltage conductivity apparatus. The third calve tested for hardness by taking a a couple of(prenominal) blue samples of each solid, putting them onto individual watch glasses and quelling with a scoopula. The relative hardness was then ranked. The 4th part was melt point and the melting point in this teddy was given in the beginning and non tested for. discovered was that loft compounds (tested were KI and NaCl) drive home higher melting points, a rgon 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 noodle 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 bewilder 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) sucrose, CHO(! s) Naphthalene, CH(S) low-voltage conductivity apparatus 6 ample test tubes test tube rack dab 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 make throat and cause headaches eye protection to keep substance out of eyeb every last(predicate) in case of spills Procedure: 1.Gather all necessary materials Part...If you take to get a full essay, companionship it on our website: OrderCustomPaper.com
