Question

Имеются водные растворы следующих веществ:AgNO3;NaI;ALCL3;HBr.Напишите молекулярные и ионные уравнения реакций,которые можно осуществить между ними

Answer 1

3AgNO3 + AlCl3 = 3AgCl ↓ + Al(NO3)3

3Ag+ + 3NO3- + Al  3+ + 3Cl- = 3AgCl + Al3+ + 3NO3-

3Ag+ + 3Cl- = 3AgCl

 

AgNO3 + NaI = AgI ↓ + NaNO3

Ag+ + NO3- + Na+ + I - = Agl↓ + Na+ + NO3-

Ag+ + l- = Agl↓

 

AgNO3 + HBr = AgBr ↓ + HNO3

Ag+ + NO3- + H+ + Br- = AgBr ↓ + H+ + NO3-

Ag+ + Br- = AgBr ↓

 

Answer 2

Molecular and Ionic Equations for Reactions between AgNO3, NaI, AlCl3, and HBr

To determine the molecular and ionic equations for reactions between the given substances, we need to consider the possible reactions that can occur. Here are the reactions that can take place:

1. AgNO3 (Silver Nitrate) and NaI (Sodium Iodide): - Molecular Equation: AgNO3 + NaI → AgI + NaNO3 - Ionic Equation: Ag⁺ + NO₃⁻ + Na⁺ + I⁻ → AgI + Na⁺ + NO₃⁻ - Net Ionic Equation: Ag⁺ + I⁻ → AgI

2. AgNO3 (Silver Nitrate) and AlCl3 (Aluminum Chloride): - Molecular Equation: AgNO3 + AlCl3 → AgCl + Al(NO3)3 - Ionic Equation: Ag⁺ + NO₃⁻ + Al³⁺ + Cl⁻ → AgCl + Al³⁺ + NO₃⁻ - Net Ionic Equation: Ag⁺ + Cl⁻ → AgCl

3. AgNO3 (Silver Nitrate) and HBr (Hydrobromic Acid): - Molecular Equation: AgNO3 + HBr → AgBr + HNO3 - Ionic Equation: Ag⁺ + NO₃⁻ + H⁺ + Br⁻ → AgBr + H⁺ + NO₃⁻ - Net Ionic Equation: Ag⁺ + Br⁻ → AgBr

4. NaI (Sodium Iodide) and AlCl3 (Aluminum Chloride): - Molecular Equation: NaI + AlCl3 → AlI3 + NaCl - Ionic Equation: Na⁺ + I⁻ + Al³⁺ + Cl⁻ → AlI₃ + Na⁺ + Cl⁻ - Net Ionic Equation: I⁻ + Al³⁺ → AlI₃

5. NaI (Sodium Iodide) and HBr (Hydrobromic Acid): - Molecular Equation: NaI + HBr → HI + NaBr - Ionic Equation: Na⁺ + I⁻ + H⁺ + Br⁻ → HI + Na⁺ + Br⁻ - Net Ionic Equation: I⁻ + H⁺ → HI

6. AlCl3 (Aluminum Chloride) and HBr (Hydrobromic Acid): - Molecular Equation: AlCl3 + 3HBr → AlBr3 + 3HCl - Ionic Equation: Al³⁺ + 3Cl⁻ + 3H⁺ + 3Br⁻ → AlBr₃ + 3H⁺ + 3Cl⁻ - Net Ionic Equation: Al³⁺ + 3Br⁻ → AlBr₃

Please note that these equations are based on the information provided and may not represent the complete set of possible reactions. It is always important to consider the specific conditions and concentrations when predicting chemical reactions.
