Solids, Solutions and Size Flashcards
What are the 3 states of matter?
-Solid
-Liquid
-Gas (vapour)
Is a Solution a single or two-phase?
-Single phase
Is a suspension or emulsion single phase or two-phase?
-Two-phase
What does equilibrium depend on in a solution, emulsion or suspension?
-Dependent on the conditions
When is an equilibrium reached?
-When no more solute can dissolve, known as a saturated solution
Types of solution- What is a Solid in Liquid?
-Solutions of non-electrolyte (non-ionic) like phenol and sucrose
-Solutions of electrolytes (from ions in solution) like strong electrolytes NaCl and weak electrolytes such as weak acids and bases
Types of solution- What is a Liquid in Liquid?
Solutions of this type can be divided into two categories:
-1) Completely miscible, e.g ethanol and water
-Miscibility: ‘Mutual solubility of components in liquid in liquid systems’
2) Partially miscible, e.g water and octanol
-Partial miscibility is affected by temperature
-Partially miscible binary liquid mixtures are used with a separating funnel to determine partition coefficients
What does miscible mean?
of liquids) forming a homogeneous mixture when added together.
Types of solution- What is a Gas in Liquid?
-Solubility of gases is determined by temperature and pressure
-Solubility generally decreases as temperature rises
-Process used in manufacture of Water For injections BP
-Solubility generally increases as pressure rises
What does homogeneous mean?
homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample
What does immiscible mean?
of liquids) not forming a homogeneous mixture when mixed
