Verified Answer
The reaction used in the experiment to verify the law of conservation ...
The correct answer is D: Both A and B.
- Precipitation Reaction: AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq) forms a solid precipitate.
- Double Displacement Reaction: AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq) involves the exchange of ions between two compounds.
- Explanation: The given reaction demonstrates both characteristics, forming a precipitate (A) and involving double displacement of ions (B), making it both a precipitation and a double displacement reaction.
- Precipitation Reaction: AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq) forms a solid precipitate.
- Double Displacement Reaction: AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq) involves the exchange of ions between two compounds.
- Explanation: The given reaction demonstrates both characteristics, forming a precipitate (A) and involving double displacement of ions (B), making it both a precipitation and a double displacement reaction.

The reaction used in the experiment to verify the law of conservation ...
The correct answer is option 'D' - Both A and B.
The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is always equal to the total mass of the products. This means that no mass is gained or lost during a chemical reaction.
To verify the law of conservation of mass, an experiment can be conducted where the masses of the reactants and products are measured before and after the reaction. This experiment can be done using various types of reactions.
1. Precipitation reaction:
In a precipitation reaction, two soluble compounds react to form an insoluble compound called a precipitate. For example, when silver nitrate (AgNO3) reacts with sodium chloride (NaCl), a white precipitate of silver chloride (AgCl) is formed. By measuring the masses of the reactants (AgNO3 and NaCl) and the product (AgCl), the law of conservation of mass can be verified.
2. Double displacement reaction:
In a double displacement reaction, the positive and negative ions of two ionic compounds exchange places to form new compounds. For example, when sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), sodium chloride (NaCl) and water (H2O) are formed. By measuring the masses of the reactants (NaOH and HCl) and the products (NaCl and H2O), the law of conservation of mass can be verified.
3. Neutralization reaction:
In a neutralization reaction, an acid reacts with a base to form a salt and water. For example, when sulfuric acid (H2SO4) reacts with sodium hydroxide (NaOH), sodium sulfate (Na2SO4) and water (H2O) are formed. By measuring the masses of the reactants (H2SO4 and NaOH) and the products (Na2SO4 and H2O), the law of conservation of mass can be verified.
Since the question asks for the category of the reaction used in the experiment to verify the law of conservation of masses, the correct answer is option 'D' - Both A and B (precipitation reaction and double displacement reaction). Both of these types of reactions can be used to demonstrate the law of conservation of mass.
