\n\n\n\nExplanation<\/strong><\/h3>\n\n\n\n
AgNO\u2083 (silver nitrate) and Na\u2082S (sodium sulfide) are both soluble in water and thus exist as ions:
AgNO\u2083 \u2192 Ag\u207a + NO\u2083\u207b
Na\u2082S \u2192 2Na\u207a + S\u00b2\u207b<\/p>\n\n\n\n
Ag\u207a pairs with S\u00b2\u207b
Na\u207a pairs with NO\u2083\u207b
This yields Ag\u2082S and NaNO\u2083<\/p>\n\n\n\n
Ag\u2082S is insoluble<\/strong> in water and will precipitate out of solution
NaNO\u2083 is soluble<\/strong> in water and remains in aqueous form<\/p>\n\n\n\n
2AgNO\u2083(aq) + Na\u2082S(aq) \u2192 Ag\u2082S(s) + 2NaNO\u2083(aq)<\/p>\n\n\n\n
2Ag\u207a(aq) + 2NO\u2083\u207b(aq) + 2Na\u207a(aq) + S\u00b2\u207b(aq) \u2192 Ag\u2082S(s) + 2Na\u207a(aq) + 2NO\u2083\u207b(aq)
Here, Na\u207a and NO\u2083\u207b ions appear on both sides and do not participate in the actual chemical change. They are spectator ions<\/strong>.<\/p>\n\n\n\n
