\(n_{AgNO_3}=1.0,5=0,5\left(mol\right);n_{HCl}=2.0,3=0,6\left(mol\right)\)
PTHH: AgNO3 + HCl → AgCl ↓ + HNO3
Mol: 0,5 0,5 0,5
Ta có: \(\dfrac{0,5}{1}< \dfrac{0,6}{1}\)⇒ AgNO3 pứ hết, HCl dư
* Vdd sau pứ = 0,5+0,6 = 1,1 (l)
\(\Rightarrow C_{M_{ddNO_3}}=\dfrac{0,5}{1,1}=0,4545M\)
\(C_{M_{ddHCldư}}=\dfrac{0,6-0,5}{1,1}=0,0909M\)
\(m_{ddAgNO_3}=500.1,2=600\left(g\right);m_{ddHCl}=300.1,5=450\left(g\right)\)
* mdd sau pứ = 600+450 = 1050 (g)
\(C\%_{ddHNO_3}=\dfrac{0,5.63.100\%}{1050}=3\%\)
\(C\%_{ddHCl}=\dfrac{\left(0,6-0,5\right).36,5.100\%}{1050}=0,348\%\)
