Which statement best describes the focus of chemistry?
The investigation of matter's properties and reactions
What is the main difference between metallic and electrolytic conductors?
Electrolytic conductors conduct electricity without undergoing chemical changes
What is the primary focus of electrochemistry?
Studying electrolyte solutions and phenomena at the atomic level
How are chemists commonly perceived in popular culture?
As white-coated scientists mixing strange liquids in a laboratory
What is a characteristic of semi-conductors like Ge, In, and Tl?
They can exhibit both N-type and P-type behavior
What are the properties of a protic polar solvent?
High dielectric constant, hydrogen bond donor and acceptor, strong solvation of cations and anions.
Give an example of an aprotic nonpolar solvent.
Aliphatic and aromatic hydrocarbons, ethers.
Define dielectric constant and its effect on conductivity.
Dielectric constant is the difference in capacitance with and without an insulator. It affects conductivity of a solvent.
How does the concept of activity differ for ideal and non-ideal processes?
For ideal processes, we use concentration ([conc.]), while for non-ideal processes we use activity (a).
What is the relationship between the activity coefficient (γ) and ions?
The activity coefficient (γ) is specific to ions and is represented by a square bracket ([]) for concentration.
