NaCl + AgNO3 => AgCl + NaNO3
nNaCl = 0.25 x 0.2 = 0.05 (mol)
Theo phương trình ==> nAgCl = 0.05 (mol)
mAgCl = n.M = 0.05 x 143.5 = 7.175 (g)
nAgNO3 = 0.05 (mol)
CM dd AgNO3 = n/V = 0.05/0.15 = 1/3M
nNaNO3 = 0.05 (mol)
Vdd sau pứ = 200 + 150 = 350ml = 0.35 (l)
CMddsau pứ = n/V = 0.05/0.35 = 1/7 (M)
nNaCl= 0.05 mol
NaCl + AgNO3 --> AgCl + NaNO3
Từ PTHH:
nAgCl=0.05 mol
mAgCl= 7.175g
nAgNO3= 0.05 mol
mAgNO3= 8.5g
C%AgNO3= 8.5/150*100%= 5.67%
CM NaNO3= 0.05/0.2=0.25M
a) PTHH: NaCl + AgNO3 \(\rightarrow\) NaNO3 + AgCl\(\downarrow\)
b) nNaCl = \(\frac{0,25.200}{1000}=0,05\left(mol\right)\)
Theo PT: nAgCl = nNaCl = 0,05(mol)
=> mAgCl = 0,05.143,5 = 7,175(g)
