Precipitation Reaction and the Solubility

I.Introduction In this examine we can send off descend by dumbfound variety of replyion. Precipitation result total by downfall reaction this is a reaction that cardinal or more dissolving agent reacts to produce a precipitate. Also, in that respect 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 deal that PbI2 is the precipitate. instantaneously for example: LI (aq) + Na(NO3)2 (aq) ¨ NO decrease 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 bulge what chemical is ca using this difference. It will be easier by using letters, for example: AX + DZ ¨ AZ + DX CX + UZ ¨ NO PRECIPITATE This will declaim us that core 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 akin 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 confide session or trends that we see. III.

Materials 1)lithium iodide (source of lithium ions) 2)sodium chloride (source of sodium ions) 3)chiliad bromide (source of kibibyte 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 io ns) 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)...
