  • 2. 

    A solution where water is the solvent.

    • Aqueous

    • Hydrate

    • Salt

    • Anhydrous

    Correct Answer
    A. Aqueous
    Explanation
    The term "aqueous" refers to a solution in which water is the solvent. In this context, it means that water is used to dissolve another substance, such as a salt or a hydrate. The term "aqueous" is commonly used in chemistry to describe solutions that involve water as the solvent. It is important to note that "aqueous" does not specify the type of solute or the concentration of the solute in the solution, it simply indicates that water is the solvent.

    Rate this question:

  • 3. 

    A positively charged ion.

    • Cation

    • Anion

    • Salt

    • Molecule

    Correct Answer
    A. Cation
    Explanation
    A positively charged ion is called a cation. It is formed when an atom loses one or more electrons, resulting in a net positive charge. Cations are attracted to negatively charged particles and are often involved in chemical reactions. An example of a cation is the sodium ion (Na+), which forms when a sodium atom loses one electron.

    Rate this question:

  • 4. 

     A negatively charged ion

    • Acidic

    • Anion

    • Cation

    • Salt

    Correct Answer
    A. Anion
    Explanation
    An anion is a negatively charged ion. In chemistry, ions are formed when atoms gain or lose electrons. When an atom gains electrons, it becomes negatively charged and is called an anion. Anions are often found in acidic substances, as acids tend to release hydrogen ions, which are positively charged. Therefore, the correct answer is anion.

    Rate this question:

  • 5. 

    A solution whose pH is less than 7.

    • Acidic

    • Basic

    • Compound

    • Molecule

    Correct Answer
    A. Acidic
    Explanation
    A solution with a pH less than 7 is considered acidic. This means that the concentration of hydrogen ions (H+) in the solution is higher than the concentration of hydroxide ions (OH-). Acids have a sour taste and can react with metals, turn litmus paper red, and have a corrosive effect on certain materials.

    Rate this question:

  • 6. 

    One of the starting materials in a chemical reaction.

    • Product

    • Reactant

    • Compound

    • Aqueous

    Correct Answer
    A. Reactant
    Explanation
    A reactant is a substance that undergoes a chemical reaction to form new products. In this context, the question is asking for the starting material in a chemical reaction. Therefore, the correct answer is "Reactant."

    Rate this question:

  • 7. 

    Material produced during a chemical reaction.

    • Product

    • Reactant

    • Cation

    • Anion

    Correct Answer
    A. Product
    Explanation
    In a chemical reaction, the product refers to the material that is formed as a result of the reaction. It is the end result or outcome of the reaction, which may be a new substance or a combination of different substances. The product is different from the reactants, which are the starting materials or substances that undergo the reaction. In this context, the correct answer is "Product" because it accurately describes the material produced during a chemical reaction.

    Rate this question:

  • 8. 

    A compound in which a specific number of water molecules is associated with each formula unit.

    • Hydrate

    • Aqueous

    • Disociate

    • Molecule

    Correct Answer
    A. Hydrate
    Explanation
    A hydrate is a compound that contains a specific number of water molecules associated with each formula unit. In other words, it is a substance that has water molecules trapped within its crystal structure. This water is not chemically bonded to the compound, but rather held by weak intermolecular forces. When the hydrate is heated, the water molecules can be released, resulting in the compound becoming anhydrous.

    Rate this question:

  • 9. 

    To separate a compound into its ions in water

    • Salt

    • Dissociate

    • Anhydrous

    • Hydrate

    Correct Answer
    A. Dissociate
    Explanation
    Dissociation refers to the process of separating a compound into its ions when it is dissolved in water. In this context, the term "dissociate" accurately describes the action of breaking apart a compound into its constituent ions in an aqueous solution. This process is commonly observed with salts, where the positive and negative ions become surrounded by water molecules, forming a solution. The other options, such as "salt," "anhydrous," and "hydrate," do not specifically refer to the process of separating a compound into ions in water.

    Rate this question:

  • 10. 

    An ionic compound composed of positively charged cations and negatively charged anions.

    • Salt

    • Acid

    • Base

    • Product

    Correct Answer
    A. Salt
    Explanation
    An ionic compound is formed when positively charged cations and negatively charged anions combine. Salt is an example of such a compound, as it is formed when a metal cation (positive) combines with a non-metal anion (negative). The positive and negative charges attract each other, forming a stable compound with a crystal lattice structure. Therefore, salt is the correct answer as it fits the description of an ionic compound composed of cations and anions.
