What is molarity (M)?
c= n (solute)/ v (L of sol)
Which has higher conductivity: 1.0 M NaCl or 0.9 M Ca(NO₃)₂?
Ca(NO₃)₂ (produces more ions)
What are electrolytes vs. non-electrolytes?
Electrolytes conduct electricity in solution; non-electrolytes do not.
What defines a base?
Contains OH⁻ and typically strong.
What defines an acid?
Contains H⁺ and donates protons.
What is a neutralization reaction?
Acid + base → salt + water
What is oxidation?
Loss of electrons
What is reduction?
Gain of electrons
Common oxidation states: F, H, O?
F = -1, H = +1, O = -2
