Question

Escreva as equações de dissociação:
Exemplo: NaOH ➡ Na+' + OH-'
H2'S ➡ 2H+' + S-2'

a)KOH ➡
b)Ca(OH) ➡
c)Fe(OH)2' ➡
d)Fe (OH)3'
e)HCl ➡
f)HNO3' ➡
g)H2'SO4' ➡

Answer 1

$a) KOH \longrightarrow K^+_{(aq)} + OH^- _{(aq)}\\b) Ca(OH)_2 \longrightarrow Ca^{2+}_{(aq)} + 2 OH^-_{(aq)}\\c) Fe(OH)_2 \longrightarrow Fe^{2+}_{(aq)} + 2 OH^-_{(aq)}\\d) Fe(OH)_3 \longrightarrow Fe^{3+}_{(aq)} + 3 OH^-_{(aq)}\\e) HCl \longrightarrow H^+_{(aq)} + Cl^-_{(aq)}\\f) HNO_3 \longrightarrow H^+_{(aq)} + NO_3^-_{(aq)}\\g) H_2SO_4 \longrightarrow 2 H^+_{(aq)} + SO_4^{2-}_{(aq)}$
