15.
2 AgNO3 + Na2SO4 ---------------- Ag2SO4 + 2 NaNO3
2 mole 1 mole
AgNO3 = 0.305M
Na2SO4 = 155.0ml of 0.274M
AgNO3 Na2SO4
M1 = 0.305M M1= 0.274M
V1= V2= 155.0ml
n1= 2 mole n2= 1 mole
M1V1/n1= M2V2/n2
0.305 x V1/2 = 0.274 x155/1
V1= 278.49 ml
V1= 278 ml
The answer is E
16.
Acetic acid is weak acid. so it undergoes partially ionisation. so it acts as weak electrolyte.
so the naswer is B.
17.
HCl is a strong acid . so it undergoes completly ionisation. so it acts as strong electrolute.
the answer is C.
18.The answer is A.
the weak acid undergoes partially ionisation.so it contains mostly molecules.
19.
K2S(aq) + Fe(NO3)2(aq) ------------------- FeS(s) + 2 KNO3(aq)
2 K+(aq) + S-2(aq) + Fe+2(aq) + 2 NO3-(aq) ---------- FeS(s) = 2 K+ (aq) + 2 NO3-(aq)
F2+2(aq) + S-2(aq) --------------------- FeS(s)
the answer is D
20.
no reaction can takes place.
The answer is E.
