\(a,PTHH:KOH+HCl\rightarrow KCl+H_2O\\ b,n_{KOH}=n_{HCl}=2\cdot0,1=0,2\left(mol\right)\\ \Rightarrow V_{dd_{HCl}}=\dfrac{0,2}{2}=0,1\left(l\right)\\ c,C_{M_{KCl}}=\dfrac{0,2}{0,1+0,1}=1M\)
Đổi 100ml = 0,1 lít
Ta có: \(n_{KOH}=2.0,1=0,2\left(mol\right)\)
a. PTHH: \(KOH+HCl--->KCl+H_2O\)
b. Theo PT: \(n_{HCl}=n_{KOH}=0,2\left(mol\right)\)
\(\Rightarrow V_{dd_{HCl}}=\dfrac{0,2}{2}=0,1\left(lít\right)=100\left(ml\right)\)
c. Ta có: \(V_{dd_{KCl}}=V_{dd_{HCl}}=0,1\left(lít\right)\)
Theo PT: \(n_{KCl}=n_{HCl}=0,2\left(mol\right)\)
\(\Rightarrow C_{M_{KCl}}=\dfrac{0,2}{0,1}=2M\)
