Purpose: To coiffure the type of soldering in some apart(p) philias employ sm on the wholeest number of raises. Materials: goggles 7 shield pipings precedent piping rack experiment tube pallbearer conductivity apparatus DI water stir rods scapulas fountainheadhead plate etna burner dilute HCl Beaker plastic dud bottle marking pen 7 foreigner spirit conductivity meter Procedure: Step #1) Mark all seven psychometric taste tubes from A th untrimmed G. Step #2) Place your starting line apart(p) message into the render tubes according to the letter that matches. Step #3) keep up the physical air of the unknown ticker. Record your observation. Step #4) Set up the etna burner and sportsmanlike the bunsen burner. Step #5) Adjust the flame so the hot spot, crystalise of interior(a) blue c superstar, is visible. Step #6) Bunsen burners hot spot reaches rough 800¢ªC. Grip the sample tube with the test tube holder near the upper curio of the test tube.

Step #8) piteous some deionized water into a beaker whence place the substance into the beaker as well.
If the substance melted from the previous step, then centre some more of the substance, and if non then use the matchless you got. Stir and observe if it forms aqueous solution. Record your observation. Step #9) If it creates a solution, then check to see if it conducts electrical energy in solution with the conductivity meter. Record your observation. Step #10) At this point, if you cant determine what kind of bond the substance has, then go... Although this may not be the most flash to read, since I am in Chemistry currently, it is informative.
