Question

Compare the solubility of silver phosphate in each of the following aqueous solutions: Clear All 0.10 M AgNO3 More soluble than in pure water. 0.10 M (NH4)3PO4 Similar solubility as in pure water. 0.10 M NaCH3COO Less soluble than in pure water. 0.10 M NH4NO3

Answer 1

Aq, PO4 Silver phosphate Ag3 P04 (8) ² 3Ag+ (ap.) + Pop? Due to presence of common ion, the solubility of springly soluble salt is decrease due to common in effect as due to pers presence y common ion, equilibrium shift to left According to Le Chatlier Principal I o.lom AgNO3 AgNO3(ap:) — Age Calo) + NO3(als since common ion Ag+ added, so its solubility decreases in Ag Noz sol so solubility is less than pure water - 17 inn Inn o Olom (NH4), P04 (N144)3 P04 Cap.) → 3N447 Cap.) + pot call) since common ion Post added, so the solubility of Ag₂ PO4 decreases Solubility is len than pure water 3 0.10M NGCH₃Coo CH3 Coo Na → 013600() that there is no common ion 80 no effect on solubility. Similar solubility as in byre water

0.10M NHaNO3 NH4NO3 Capi) - here again no common im Nn4+ NO3- so similar solubility as bure water
