Write down the hydrolysis equations in molecular and ionic form, indicate the medium and type of hydrolysis for the following salts: Al2S3, K2S, FeCl2, CaCl2

Let’s compose the equations:
1) Al2S3 = 2Al3 + 3S2;
HOH = H + + OH-;
Al2S3 + 6H2O = 2Al (OH) 3 + 3H2S;
Complete hydrolysis. Wednesday neutral PH = 7.
2) K2S = 2K + + S2-;
2K + + S2- + H2O = K + + OH- + K + + HS- – complete ionic equation;
S2- + H2O = HS- + OH- – abbreviated equation;
K2S + H2O = KOH + KHS – molecular equation;
Alkaline medium pH> 7.
3) FeCl2 = Fe2 + + 2Cl-;
Fe2 + + 2Cl- + H2O = FeOH + + Cl- + H + + Cl;
FeOH + + H2O = Fe (OH) 2 + H +;
FeCl2 + H2O = Fe (OH) Cl + HCl;
Acidic medium pH <7.
4) CaCl2 = Ca2 + + 2Cl-;
Ca2 + + 2Cl- + H2O = CaOH + + Cl- + H + + Cl-;
Ca2 + + H2O = CaOH + + H +;
CaCl2 + H2O = Ca (OH) Cl + HCl;
Acidic medium pH <7.
