HCl + AgNO3 ➜ AgCl↓ + HNO3
\(n_{HCl}=0,2\times2=0,4\left(mol\right)\)
\(n_{AgNO_3}=0,3\times2=0,6\left(mol\right)\)
Theo PT: \(n_{HCl}=n_{AgNO_3}\)
Theo bài: \(n_{HCl}=\dfrac{2}{3}n_{AgNO_3}\)
Vì \(\dfrac{2}{3}< 1\) ⇒ dd HCl hết, dd AgNO3 dư
Theo PT: \(n_{AgCl}=n_{HCl}=0,4\left(mol\right)\)
\(\Rightarrow m_{AgCl}=0,4\times143,5=57,4\left(g\right)\)
Dung dịch B gồm: AgNO3 dư và HNO3
Theo PT: \(n_{AgNO_3}pư=n_{HCl}=0,4\left(mol\right)\)
\(\Rightarrow n_{AgNO_3}dư=0,6-0,4=0,2\left(mol\right)\)
Theo PT: \(n_{HNO_3}=n_{HCl}=0,4\left(mol\right)\)
\(\Sigma n_{ctB}=n_{AgNO_3}dư+n_{HNO_3}=0,2+0,4=0,6\left(mol\right)\)
\(\Sigma m_{ddB}=0,2+0,3=0,5\left(l\right)\)
\(\Rightarrow C_{M_{ddB}}=\dfrac{0,6}{0,5}=1,2\left(M\right)\)
