Question

The chemical reaction that are used in the anion spot tests in this experiment are the most part simple precipitation or acid-base reactions. Given the information in each test procedure, try to write the net ionic equation for the key reaction in each test.

a. CO3 2-

b. SO4 2-

c. PO4 3- (Reactions are HPO4 2-, NH4+, MoO4 2-. and H+; products are (NH4)3PO4* 12 MoO3 and H2O; no oxidation or reduction occurs.)

d. SO3 -2

e. SCN-

f. Cl-

g. NO3- (Take as reactants Al and NO3-; as products NH3 and AlO2-; final equation also

contains OH- and H2O as reactants.)

i need the net iconic equation for each of these!!

Explanation / Answer

a) 2 H+ (aq) + CO3 2- (aq) --------> H2O (l) + CO2 (g)

b) Ba2+ (aq) + SO4 2- (aq) -----------> BaSO4

c) HPO4 2- (aq) + 3 NH4 + (aq) + 12 MoO4 2- (aq) + 23 H+ (aq) -----------> (NH4)3PO4·12MoO3 (s) + 12 H2O (l)

d)

e) Ag+ (aq) + SCN- (aq) ----------> AgSCN (s)

f) Ag + (aq) + Cl- (aq) -----------> AgCl (s)

g) Al + NO+3 + NaOH -----------> NH3 + AlO-
