The pKa of carbonic acid H2CO3is 6. If you made up an ether solution of chemicals HX and HY in a separatory funnel, andthen added an aqueous solution of sodium bicarbonate NaHCO3 to that separatory funnel,would both HX and HY stay in the ether layer? Or would either or both of them transfer intothe aqueous layer? If one goes into the water layer, will it be in it’s neutral HX/HY form, or init’s deprotonated anionic form?1) A polyester made from sebacic acid (CAS# 111-20-6) and 1,6-hexanediol (CAS# 629-11-8) has the molecular weight fractionation listed below.
