Data Table 2: Experimental results. When conducting the reactions as your lab manual outlines, if you see a mixture become cloudy then you know a reaction has happened. However, if the reaction mixture remains transparent, even if the color has changed, then there has been no reaction; all of the dissolved materials continues to remain dissolved. For your data table you will record one of two entries for each reaction. a} If there is a precipitate formed, you will record "ppt" for precipitate. if there is a ppt formed, describe what it looks like in the same box in the data table {for example: ”ppt, cloudy, white”). b) If there is no precipitate formed, you will record "NR” for no reaction.

This is the ionic equation !! 5) For the Net Ionic equation. we need to eliminate ions that do not change from reactants to products (aka
spectator ions] There are two steps:
a) Cancel ions that do not contribute to the formation of the solid on both sides of the equation: 3 32.21%}; s Nag—(w) + 5 Natlgg) + 2 ma- (gg) a Ba3(PD4)1(s) + s He‘d-(351) + a met-(99) b) Write the net ionic equation with the remaining ions and solid: 3332+ ‘95); 2P043- (as) —’ 333(P04h [5} This is the net ionic equationi.’ For full credit, please remember to do the following:
0 Include charges on ions.
0 Use sub and superscripts properly, e.g.: ”2P043- -) Ba3(P04l1”, not ”2PD43- -) Ba3(PD4)2” or P045};
I Write the correct chemical formula for the precipitate. 0 Balance the net ionic equation. Reaction 1: Chemical:
