Question

q9

Using the solubility table, predict whether a reaction occurs or no reaction occurs for each of the following double-replacement reactions: a) AgC2H2O2(aq) + Srl2(aq) → [Select] b) FeSO4(aq) + CuCl2(aq) → [Select] c) NaOH(aq) + CO(NO3)2(aq) – [ Select]

Answer 1

AgC2H3O2 is silver acetate upon reaction with strontium iodide produce a precipitate of
AgI.
2AgC2H3O2(aq) + SrI2(aq) ---> Sr(C2H3O2)2(aq) + 2AgI(s)
Hence
yes ,reaction occurs
****************
FeSO4(aq) +CuCl2(aq) --> No reaction
***************************************

2NaOH(aq) + Co(NO3)2(aq) --> Co(OH)2(s) +2 NaNO3(aq)

precipitate of co(OH)2 forms.

Hence

Reaction occurs
