Solids and solution size

Question 1

Crystalline

Polymorphs

Answer 1

Different type or formation of crystalline structure (stability so ability to dissolve)

Question 2

Crystalline

Co-crystals

Answer 2

Single phase materials composed of two or more different molecular or ionic compounds

Question 3

Amorphous

Answer 3

No structure to the arrangement of its structure
Glass is amorphous disorder in the molecules

Question 4

Triple point

Answer 4

• Exists as all three states
• Critical point combination of gas and liquid together

Question 5

Solution

Answer 5

Mixture of 2 or more components that forms a single phase at a homogenous to molecular level

Question 6

Solvent

Answer 6

• The component which determines the phase syrup bp water is solvent determines the phase

Question 7

Solute

Answer 7

• The other component which are dispersed as molecules or ions through solvent (in solution)

Question 8

Dissolution

Answer 8

Solid molecules move to solution form

Question 9

Solution vs Pharmaceutical Particles

Answer 9

• Single phase solution cannot be seen by magnifying
• Eventually equilibrium has been reached no more solute can be dissolved ‘saturated solution’
  Heat from suspension to solution

Question 10

Solid in liquid

Answer 10

• Solutions of non-electrolyte
• Solubility of weak acid and weak bases

Question 11

Liquid in liquid

Answer 11

• Miscible liquid ethanol in water one dissolves completely in the other
• Partially miscibility is effected by temperature use separating funnel determined by concentration

Question 12

Gas in liquid

Answer 12

• Solubility of gas determined by temperature & pressure
• Decrease of solubility if temp rises
  Water for injections in BP & chromatography HPLC
