Description
Our listener’s choice recaps three topics: (R)ICE tables, titrations and buffers. We start with the RICE table - what does it actually stand for? (0:49). RICE tables are best explained with an example. In our case: The reaction of gaseous hydrogen with gaseous chlorine to form gaseous hydrogen chloride - a reaction that has a K = 49. And we are calculating the concentrations at equilibrium (1:44)! Two important tips for RICE tables: (1) practice, practice, practice; (2) make assumptions (4:09).Our next two topics are connected: titrations and buffers. We start with the titration of a strong acid/strong base and discuss the calculation of the pH at several points along the titration curve (6:01). Our second example is the titration of a weak acid with a strong base. Again, we discuss the pH calculations along the titration curve, but then focus on buffers, which are formed when the weak acid is partially neutralized (7:29). The episode defines buffers and describes how they work (8:00). Moving along the titration curve, we discuss the calculations for buffers and the midway point of the titration (9:18), the calculations at equivalence point (10:03) and beyond the equivalence point.Question: What will be the approximate pH of an equimolar solution of NH3 and HCl?Thank you for listening to The APsolute RecAP: Chemistry Edition!(AP is a registered trademark of the College Board and is not affiliated with The APsolute RecAP.
