What is a solution
if a drug is dissolved in water, which s the solute and which is the solvent?
besides solid in water, what other types of solutions exist?
What are the three steps in dissolution of solid in liquid?
What is a saturated solution?
what is a supersaturated solution?
True or False
if the solute-solvent forces are strong enough to compensate for the forces that are broken, then it is likely that the solid will dissolve in a solvent
True or False
The overall heat exchanged in dissolution process is called entropy
What effect will heating the solvent have on dissolution of a drug which has a negative heat of solution?
What effect will heating solvent have when a drug has a positive heat of solution?
True or False
If a drug dissolving in solvent has negative heat of solution, we have an endothermic process
What is the dielectric constant
Which of the following solvents will have the highest dielectric constant:
water
alcohol
benzene
If we have a polar drug, which solvent will it best dissolve in?
water or benzene
Alcohol has a lower dielectric constant than water and is classed as semi-polar solvent
True or False
Write the Noyes-Whitney equation (used to describe rate of dissolution)
