1,
\(\begin{array}{l}
FeS{O_4} + 2NaOH \to Fe{(OH)_2} + N{a_2}S{O_4}\\
F{e^{2 + }} + S{O_4}^{2 - } + 2N{a^ + } + 2O{H^ - } \to Fe{(OH)_2} + 2N{a^ + } + S{O_4}^{2 - }\\
F{e^{2 + }} + 2O{H^ - } \to Fe{(OH)_2}
\end{array}\)
2,
\(\begin{array}{l}
F{e_2}{(S{O_4})_3} + 6NaOH \to 2Fe{(OH)_3} + 3N{a_2}S{O_4}\\
2F{e^{3 + }} + 3S{O_4}^{2 - } + 6N{a^ + } + 6O{H^ - } \to 2Fe{(OH)_3} + 6N{a^ + } + 3S{O_4}^{2 - }\\
F{e^{3 + }} +3 O{H^ - } \to Fe{(OH)_3}
\end{array}\)
3,
\(\begin{array}{l}
{(N{H_4})_2}S{O_4} + BaC{l_2} \to BaS{O_4} + 2N{H_4}Cl\\
