Q
Solute
A
(substance being dissolved; least amount)
5
Q
Solvent
A
(the dissolving medium; great amount)
6
Q
Dilute
A
(relatively little solute
7
Q
Concentrated
A
(relatively large amount of solute)
8
Q
Strong electrolyte
A
virtually no solute molecules in water (complete dissociation); bright light
9
Q
Weak electrolyte
A
solute dissociates to slight extent (incomplete dissociation or creation of ions due to the reaction with water); dim light
10
Q

A
no dissociation, dispersed; no light
