Problem: Is each compound soluble or insoluble in water?(a) NiS(b) Mg3(PO4)2(c) Li2CO3(d) NH4Cl

FREE Expert Solution

(a) NiS

Sulfides (S2–) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.), ammonium ion (NH4+), Ca2+, Sr2+, and Ba2+

NiS → insoluble


(b) Mg3(PO4)2

Phosphates (PO43–) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.) and ammonium ion (NH4+)

Mg3(PO4)2 → insoluble
