Question

10.29 Classify the following reactions as precipitation, acid-base, or redox. a, 2 SiS, (s) 4 Si (s) + S8 (s) b. 3 BaCl2 (aq) + 2 LisPOs (aq) 6 LiCI (aq) +Bas(PO)2 (s) c. Ni(CO)2 (aq) + Zn (s) ? Zn(CIO)2 (aq) + Ni (s) d. HF (aq) + LiOH (aq) -> H2O (l) + LiF (aq) 10.39 For each of the combinations given, determine whether or not a reaction occurs when the two aqueous solutions are combined. For each reaction that does happen, determine the pr and balance the equation. b. NH4Cl(aq) + LiOH(aq) ? ? c. NazSOs(aq) + HBr(aq) >

Explanation / Answer

Ana 10.29 :

When the aqueous solutions lead to the formation of a solid product , it is called as precipitation reaction. when one species is oxidised and the other is reduced in the reaction , the reaction is called as redox. When acid and base combine together to form salt and water , the reaction is called as acid-base reaction.

So here :

a) redox

b) precipitation

c) redox

d) acid - base
