Question

Скласти молекулярне повне та скорочене іонне рівняння KOH+AICI3-> HBr+Zn(OH)2->

Answer 1

3KOH + AICI₃=3KCI + AI(OH)₃↓
3K⁺ + 3OH⁻ + AI³⁺ + 3CI⁻ = 3K⁺ + 3CI⁻ + AI(OH)₃↓
 3OH⁻ + AI³⁺  =  AI(OH)₃↓

2HBr+Zn(OH)₂ = ZnBr₂ + 2H₂O
2H⁺ + 2Br⁻ +Zn(OH)₂ = Zn²⁺ + 2Br⁻ + 2H₂O
2H⁺ +Zn(OH)₂ = Zn²⁺+ 2H₂O

Answer 2

Molecular Equation:

The molecular equation for the reaction between KOH and AlCl3 is:

KOH + AlCl3 -> H2O + KCl + Al(OH)3

Ionic Equation:

To write the ionic equation, we need to break down the reactants and products into their respective ions:

Reactants: - KOH dissociates into K+ and OH- ions: KOH -> K+ + OH- - AlCl3 dissociates into Al3+ and Cl- ions: AlCl3 -> Al3+ + 3Cl-

Products: - H2O remains as H2O - KCl dissociates into K+ and Cl- ions: KCl -> K+ + Cl- - Al(OH)3 dissociates into Al3+ and OH- ions: Al(OH)3 -> Al3+ + 3OH-

Putting it all together, the ionic equation is:

K+ + OH- + Al3+ + 3Cl- -> H2O + K+ + Cl- + Al3+ + 3OH-

Net Ionic Equation:

To write the net ionic equation, we eliminate the spectator ions (ions that appear on both sides of the equation and do not participate in the reaction). In this case, the spectator ions are K+ and Cl-.

The net ionic equation is:

OH- + Al3+ -> H2O + Al(OH)3

Molecular Equation:

The molecular equation for the reaction between HBr and Zn(OH)2 is:

2HBr + Zn(OH)2 -> 2H2O + ZnBr2

Ionic Equation:

To write the ionic equation, we need to break down the reactants and products into their respective ions:

Reactants: - HBr dissociates into H+ and Br- ions: 2HBr -> 2H+ + 2Br- - Zn(OH)2 dissociates into Zn2+ and 2OH- ions: Zn(OH)2 -> Zn2+ + 2OH-

Products: - H2O remains as H2O - ZnBr2 dissociates into Zn2+ and 2Br- ions: ZnBr2 -> Zn2+ + 2Br-

Putting it all together, the ionic equation is:

2H+ + 2Br- + Zn2+ + 2OH- -> 2H2O + Zn2+ + 2Br-

Net Ionic Equation:

To write the net ionic equation, we eliminate the spectator ions (ions that appear on both sides of the equation and do not participate in the reaction). In this case, the spectator ions are Zn2+ and 2Br-.

The net ionic equation is:

2H+ + 2OH- -> 2H2O
