\(n_{CO2}=0,25\left(mol\right);n_{NaOH}=0,2\left(mol\right)\)
a, Khi tạo NaHCO3:
\(n_{NaOH}=n_{CO2}\rightarrow0,2x=0,25\)
\(\Leftrightarrow x=1,25\left(1\right)\)
\(n_{NaHCO3}=n_{CO2}=0,25\left(mol\right)\)
\(\rightarrow CM_{NaHCO3}=\frac{0,25}{1,25}=0,2M\)
b, Khi tạo Na2CO3:
nNaOH= 2nCO2 => 0,2x= 0,5
\(\Leftrightarrow z=2,5\left(2\right)\)
\(n_{Na2CO3}=n_{CO2}=0,25\left(mol\right)\)
\(\rightarrow CM_{Na2CO3}=\frac{0,25}{2,5}=0,1\left(M\right)\)
c, Khi 1,25 < V < 2,5 thì tạo 2 muối
