Answer 1

BaCl₂ + Na₂SO₄ = BaSO₄ + 2NaCl
Ba⁺² + SO₄⁻² = BaSO₄

Fe + CuCl₂ = FeCl₂ + Cu
Fe + Cu⁺² = Fe⁺² + Cu

2NaOH + FeCl₂ = Fe(OH)₂ + 2NaCl
2OH⁻ + Fe⁺² = Fe(OH)₂

K₂CO₃ + 2HNO₃ = 2KNO₃ +CO₂ + H₂O
CO₃⁻² + 2H⁺ = CO₂ + H₂O

Answer 2

Types of Reactions Involving Salts

1) Salt + Acid = Another Salt + Another Acid - When a salt reacts with an acid, it can form another salt and another acid. - For example, sodium chloride (salt) reacts with sulfuric acid to form sodium sulfate (another salt) and hydrochloric acid (another acid) [[1]].

2) Salt + Base = Another Salt + Another Base - When a salt reacts with a base, it can form another salt and another base. - For example, sodium chloride (salt) reacts with sodium hydroxide (base) to form sodium hypochlorite (another salt) and water (another base) [[2]].

3) Salt1 + Salt2 = Salt3 + Salt4 - When two salts react, they can form two different salts. - For example, silver nitrate (salt1) reacts with sodium chloride (salt2) to form silver chloride (salt3) and sodium nitrate (salt4) [[3]].

4) Salt + Metal = Another Salt + Another Metal - When a salt reacts with a metal, it can form another salt and another metal. - For example, copper sulfate (salt) reacts with iron (metal) to form iron sulfate (another salt) and copper (another metal) [[4]].

Molecular and Ionic Equations

a) Barium Chloride + Sodium Sulfate - Molecular Equation: BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2NaCl(aq) - Ionic Equation: Ba2+(aq) + 2Cl-(aq) + 2Na+(aq) + SO4^2-(aq) → BaSO4(s) + 2Na+(aq) + 2Cl-(aq) [[5]]

b) Iron(II) Chloride + Copper(II) - Molecular Equation: FeCl2(aq) + CuSO4(aq) → FeSO4(aq) + CuCl2(aq) - Ionic Equation: Fe2+(aq) + 2Cl-(aq) + Cu2+(aq) + SO4^2-(aq) → FeSO4(aq) + Cu2+(aq) + 2Cl-(aq) [[6]]

c) Sodium Hydroxide + Iron(III) Chloride - Molecular Equation: NaOH(aq) + FeCl3(aq) → Fe(OH)3(s) + NaCl(aq) - Ionic Equation: Na+(aq) + OH-(aq) + Fe3+(aq) + 3Cl-(aq) → Fe(OH)3(s) + Na+(aq) + Cl-(aq) [[7]]

d) Potassium Carbonate + Nitric Acid - Molecular Equation: K2CO3(aq) + 2HNO3(aq) → 2KNO3(aq) + H2O(l) + CO2(g) - Ionic Equation: 2K+(aq) + CO3^2-(aq) + 2H+(aq) + 2NO3-(aq) → 2K+(aq) + 2NO3-(aq) + H2O(l) + CO2(g) [[8]]
