Question
The solid present after aqueous solutions of hydrochloric acid and silver nitrate is:
a. Hydrochloric acid b. Silver nitrate c. Silver chloride d. Nitric acid
Classify the reaction HNO3(aq) + KOH(aq) KNO3(aq) + H2O(l):
a. Acid-Base b. Precipitation c. Both d. Neither
Classify the reaction Pb(NO3)2(aq) + K2SO4(aq) PbSO4(s) + 2 KNO3(aq):
a. Acid-Base b. Precipitation c. Both d. Neither
Classify the reaction Cu(s) + 2 AgNO3(aq) Cu(NO3)2(aq) + 2 Ag(s):
a. Acid-Base b. Precipitation c. Both d. Neither
Please show any work
Explanation / Answer
1) AgCl Is the only PPT, All nitrates are always soluble
2) Its a acid base neutrlisation reaction as water and Salt is formed
3) its a Precipitation reaction as PbSO4 is formed
4) Its a Redox reaction. So neither is the answer .
Copper is getting oxidised whereaas Silver is converted to metallic state,
