Question

1. Draw a picture representing a molecular-level view of the two solutions used in Reaction A before mixing and a picture of the solution that results after they are mixed. (3 pictures total)

                                                          +

                    

                       Pb(NO₃)₂ (aq)                                KI (aq)                                   mixture after the

                                                                                                                                  reaction

Data Table 1:

Reaction	Observations
A: Pb(NO3)2 + KI	Powdery appearance, stuck to the walls of the test tube, solution has a yellow color
B/C: NiCl2 + AgNO3	Powdery white, percipate accumalted as pellets at the bottom
D: H2SO4 + Indicator	Yellow color when indicator added
E: NaOH + Indicator	Dark blue when indicator is added
F: H2SO4 + NaOH	Yellow with 10 drops, then after the 23rd drop turned blue
G: Na2CO3 + H2SO4	After 20 drops Na2CO3 dissolved, after two drops of indicator it turns a dark blue after 20 drops of H2SO4 a gas is produced and changes to yellow, adding more sulfuric acid didn’t produce more bubbles
H: Mg + H2SO4	Solid magnesium strip no longer visible
