🗑
|
||||
Mixture | A blend of two or more kinds of matter, each of which retains its own identity and properties.
🗑
|
||||
Homogeneous | Having a uniform composition throughout.
🗑

Suspension | A mixture in which the particles in the solvent are so large that they settle out unless the mixture is constantly stirred or agitated.
🗑
|
||||
Colloid | A mixture consisting of particles that are intermediate in size between those in solutions and suspensions forming mixtures known as colloid dispersions.
🗑
|
||||
Disassociation | The separation of ions that occurs when an ionic compound dissolves.
🗑
|
||||
Electrolyte | A substance that dissolves in water to give a solution that conducts electric current.
🗑

🗑
|
||||
Base | Substance which gives off hydroxide ions (OH-) in solution.
🗑

🗑
|
||||
Concentration | The amount of solute in a solution.
