CHEM 1301 exam 2 review questions with accurate || || || || || || || ||
detailed answers ||
solution - ✔✔homogeneous mixture that has 2 parts, solvent & solute
|| || || || || || || || || ||
solvent - ✔✔a substance that does the dissolving
|| || || || || || ||
ex. water
||
solute - ✔✔a substance that is dissolved within the solvent
|| || || || || || || || ||
ex. salt
||
aqueous solutions of ionic compounds - ✔✔have positive and negative electrical charges
|| || || || || || || || || || ||
water dissolves many ionic compounds because - ✔✔of the polar nature
|| || || || || || || || || || ||
ex. water makes KCl (solid) separate
|| || || || ||
in water soluble ionic compounds - ✔✔solvent solute attraction is stronger
|| || || || || || || || || ||
solute solute is weaker
|| || ||
in water insoluble ionic compounds - ✔✔solvent solute is weaker
|| || || || || || || || ||
solute solute is stronger
