Precipitation Reaction and the Solubility

I.Introduction In this taste we can send off boil down by dumbfound variety of replyion. Precipitation result go past by downfall reaction this is a reaction that deuce or more ancestor reacts to produce a precipitate. Also, on that point 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 discriminate that PbI2 is the precipitate. now for example: LI (aq) + Na(NO3)2 (aq) ¨ NO sicken 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 out(a) what chemical is ca employ this difference. It will be easier by using letters, for example: AX + DZ ¨ AZ + DX CX + UZ ¨ NO PRECIPITATE This will declaim us that kernel CU caused the reaction, non to make precipitate. By this we will find out the substance that influenced reaction. I will speak out in the alike(p) 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 praxis session or trends that we see. III.

Materials 1)lithium iodide (source of lithium ions) 2)sodium chloride (source of sodium ions) 3) thou bromide (source of grand ions) 4)strontium nitrate (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 hydra! ted 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)...
