n order to prepare for a qualitative analysis experiment, Felix is predicting whether small samples of several pairs of 0.10 M control solutions will form a precipitate when mixed. He uses the table of solubility values provided as well as the general solubility guidelines in the chempendix. Solubilities of Alkaline Earth Salts (g/100 g H2O, at 20−25∘C) OH− CO2−3 SO2−4 CrO2−4 C2O2−4 Mg2+ 0.00069 0.18 35.7 54.8 0.038 Ca2+ 0.16 0.00066 0.205 13.2 0.00061 Sr2+ 2.25 0.00034 0.135 0.106 0.005 Ba2+ 4.91 0.0014 0.00031 0.00026 0.0075 For each pair of compounds, predict the formula for the precipitate that Felix will see when he mixes the solutions in lab. If no precipitate forms, enter NP for no precipitate.
