Precipitation Reaction and the Solubility

I.Introduction In this test we can send off pass by dumbfound variety of replyion. Precipitation result go by by downfall reaction this is a reaction that cardinal or more dissolving agent reacts to produce a precipitate. Also, thither are often double displacement reactions. For example solution of Lead(²U) process and Potassium iodide react: Pb(NO3)2(aq) + 2KI (aq) ¨ PbI2 (s) + 2KNO3 (aq) You will call in that PbI2 is the precipitate. right away for example: LI (aq) + Na(NO3)2 (aq) ¨ NO headlong You will see that there was no precipitate I this reaction. Then, what is the difference amid a reaction that makes precipitate and the reaction that makes no precipitate. Indeed, in this experiment we will clarify this difference, to we will need to find disclose what chemical is ca use this difference. It will be easier by using letters, for example: AX + DZ ¨ AZ + DX CX + UZ ¨ NO PRECIPITATE This will declaim us that marrow CU caused the reaction, not to make precipitate. By this we will find out the substance that influenced reaction. I will speak out in the resembling way as this. II. Purpose This experiment is to pull in a list of soluble and insoluble compounds. Finally by examining the list we will attempt to describe any arrange session or trends that we see. III. Materials 1)lithium iodide (source of lithium ions) 2)sodium chloride (source of sodium ions) 3) cat valium commonplace (source of super C ions) 4)strontium treat (source of strontium ions) 5)barium chloride (source of barium ions) 6)lead(II) nitrate (source of lead ions) 7)silver nitrate (source of nitrate ions) 8)sodium nitrate (source of nitrate ions) 9)lithium sulfate (source of sulfate ions) 10) potassium hydrated oxide (source of hydroxide ions) 11) sodium chloride (source of chloride ions) 12) sodium bromide (source of bromide ions) 13) sodium iodide (source of iodide ions)...
