Answer:
0.0039 mol/L
The molar solubility is 0.0039 mol/L, thus the common ion effect has reduced the solubility from 0.016 mol/L for Ag2SO4 in pure water to 0.0039 mol/L in the Na2SO4 solution.

I’m sorry what??...........
not 100% sure about significant figures. density might be rounded weirdly, not sure. Idk how to find hardness, so I just found the mineral before hardness, and used the hardness of that mineral
Answer:
The pH decreases very quickly, more quickly than earlier or later in the titration.
I think because SA-SB titration have the straight line where the equivalence point is where pH change is very steep and fast. Also pH is gonna decrease because after equivalence point you have more acid then base.
