What is the definition of a colligative property, and can you provide an example?
✔✔ A colligative property is a property of a solution that depends on the number of solute
particles in a given amount of solvent, rather than the identity of the solute. Examples include
boiling point elevation and freezing point depression.
What is the definition of a redox reaction, and what are its key components?
✔✔ A redox reaction, or reduction-oxidation reaction, involves the transfer of electrons between
substances, where one substance is oxidized (loses electrons) and another is reduced (gains
electrons).
What does the term "molarity" refer to in solution chemistry?
✔✔ Molarity refers to the concentration of a solution expressed as the number of moles of solute
per liter of solution.
How is the term "enthalpy" defined in thermochemistry?
✔✔ Enthalpy is a measure of the total heat content of a system, used to describe heat changes
during chemical reactions at constant pressure.

, What is the definition of a buffer solution, and how does it function in maintaining pH?
✔✔ A buffer solution is a solution that resists changes in pH upon the addition of small amounts
of an acid or a base, due to the presence of a weak acid and its conjugate base or a weak base and
its conjugate acid.
What is the definition of a coordination compound, and what are its essential components?
✔✔ A coordination compound consists of a central metal atom or ion bonded to a set of
surrounding ligands, which are molecules or ions that donate electron pairs to the metal.
What does "activation energy" mean in the context of chemical reactions?
✔✔ Activation energy is the minimum energy required for reactants to transform into products
during a chemical reaction.
What is the definition of an isotonic solution, and why is it important in biological systems?
✔✔ An isotonic solution has the same osmotic pressure as the fluid inside a cell, preventing net
movement of water into or out of the cell, which is crucial for maintaining cell shape and
function.
