The Correct Answer and Explanation is :
Here are the balanced chemical equations along with explanations for each reaction:
Reaction 1: Neutralization Reaction
Balanced Chemical Equation:
[
\text{HCl} (aq) + \text{NaOH} (aq) \rightarrow \text{NaCl} (aq) + \text{H}_2\text{O} (l)
]
Net Ionic Equation:
[
\text{H}^+ (aq) + \text{OH}^- (aq) \rightarrow \text{H}_2\text{O} (l)
]
Explanation:
This is a neutralization reaction where hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), a strong base, to form sodium chloride (NaCl) and water (H₂O). Since all the ions are soluble in water except for water itself, the net ionic equation only includes the hydrogen ion (H⁺) and hydroxide ion (OH⁻) forming water.
Reaction 3: Unknown CH₃COO and Noot
Since “CH₃Cool & Noot” does not correspond to a known chemical reaction, I’ll assume you meant a reaction involving acetic acid (CH₃COOH) and NaOH.
Balanced Chemical Equation:
[
\text{CH}_3\text{COOH} (aq) + \text{NaOH} (aq) \rightarrow \text{CH}_3\text{COONa} (aq) + \text{H}_2\text{O} (l)
]
Net Ionic Equation:
[
\text{CH}_3\text{COO}^- (aq) + \text{H}^+ (aq) + \text{Na}^+ (aq) + \text{OH}^- (aq) \rightarrow \text{CH}_3\text{COO}^- (aq) + \text{Na}^+ (aq) + \text{H}_2\text{O} (l)
]
Since sodium acetate (CH₃COONa) remains in solution, the net ionic equation simplifies to:
[
\text{H}^+ (aq) + \text{OH}^- (aq) \rightarrow \text{H}_2\text{O} (l)
]
Explanation:
This is another acid-base neutralization reaction, but instead of a strong acid, acetic acid (a weak acid) reacts with NaOH to form sodium acetate and water. The acetate ion remains in solution, so it does not appear in the net ionic equation.
Reaction 5: Precipitation Reaction
Given reactants: Na₃PO₄ + FeCl₃
Balanced Chemical Equation:
[
\text{Na}_3\text{PO}_4 (aq) + \text{FeCl}_3 (aq) \rightarrow \text{FePO}_4 (s) + 3 \text{NaCl} (aq)
]
Net Ionic Equation:
[
\text{Fe}^{3+} (aq) + \text{PO}_4^{3-} (aq) \rightarrow \text{FePO}_4 (s)
]
Explanation:
This is a precipitation reaction where sodium phosphate (Na₃PO₄) and iron(III) chloride (FeCl₃) react to form iron(III) phosphate (FePO₄), an insoluble compound that precipitates out of solution, and sodium chloride (NaCl), which remains dissolved in water. The net ionic equation only includes the ions that form the solid precipitate.
Overall Explanation (300 Words):
In these reactions, we see different types of chemical processes.
- Acid-Base Neutralization: In the first two reactions, a strong acid (HCl) and a weak acid (CH₃COOH) react with a strong base (NaOH). These reactions result in the formation of water and a salt (NaCl or CH₃COONa). The presence of water as a product confirms a neutralization reaction.
- Net Ionic Equations in Neutralization: The key takeaway from these reactions is that strong acids and bases dissociate completely in water, meaning that HCl and NaOH completely break into their ions. The net ionic equation simplifies to H⁺ + OH⁻ → H₂O, as the spectator ions (Na⁺ and Cl⁻) do not participate directly in the reaction.
- Precipitation Reaction: The third reaction involves double displacement, where Fe³⁺ and PO₄³⁻ combine to form FePO₄, which is insoluble in water. The insolubility of FePO₄ is confirmed using solubility rules, as most phosphates except for those of alkali metals are insoluble. The net ionic equation shows only the ions that contribute to precipitate formation.
- Different Chemical Reaction Types: These reactions illustrate acid-base neutralization (first two reactions) and precipitation (third reaction). Acid-base reactions involve proton transfer, while precipitation reactions involve the formation of an insoluble product.
Understanding these reactions is important in chemistry because they help us predict reaction products, solubility, and ionic interactions. These concepts are widely applicable in fields such as medicine, environmental science, and industrial chemistry.
