\(n_{H_2SO_4}=0,1.0,5=0,05\left(mol\right)\)
\(PT:H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O\)
vậy: 0,05------------->0,1-------->0,05(mol)
b) do đó: \(V_{ddKOH}=\dfrac{n}{C_M}=\dfrac{0,1}{0,2}=0,5\left(lít\right)\)
c) \(m_{K_2SO_4}=n.M=0,05.174=8,7\left(g\right)\)
\(C_{M_{K_2SO_4}}=\dfrac{n}{V}=\dfrac{0,05}{0,1+0,5}\approx0,083\left(M\right)\)
a) H2SO4+2 KOH -> K2SO4+ 2H20
b) 100ml= 0,1 l
nH2SO4=0,5*0.1=0,05(mol)
