Mastering Ideal, Intrinsic, and Regular Solubilities

Why are there so many types of solubility? There's ideal solubility, intrinsic solubility and plain old regular solubility. Are they the same or different? Do all molecules have these solubilities or are some a special case? And why should we even care? That's what we explore in this video. Find out why we measure solubility experimentally but calculate ideal solubility. And why compounds that ionise have an intrinsic solubility. You'll be saturated with information by the end!

Thanks a lot. those are very confusing concepts. After your explaination, It became crystal clear.

Could you please also explain what is kinetic solubility which was often mentioned in some of JMC paper?

When a material can dissolve very fast (say, if it's amorphous) the molecules will go into solution rapidly and the concentration of the solution may exceed the thermodynamic (equilibrium) solubility. When this happens the solution is supersaturated and sometimes the term kinetic solubility is used. Over time any molecules dissolved in excess of solubility will precipitate, but if this process takes a bit of time (say a few hours) then kinetic solubility is useful for medicines, because a higher concentration of drug will be achieved in the GI tract.
