a) Predict whether fumarate or maleate will have greater electrophoretic mobility. Cis-smaller than trans CO2 CO2 fumarate maleate b) Electrophoresis is run with the injection end positive and the detection end negative with a buffer with pH = 8.5. The charge on both ions is -2 at pH = 8.5. The electroosmotic flow is greater than the electrophoretic flow. Predict the order of elution of these two ions. At pH = 4.0, both anions have a charge of -1. At this pH, the injection end is negative, and the detection end is positive. Why is the polarity switched at lower pH?

The membrane potential for a Ca2+ Ion Selective Electrode develops as the result of a difference in the extent of the complexation reaction below. Ca+2(aq) + 2(C10H21O)2PO2- (mem) -> Ca(C10H21O)2PO2-)2 mem). This ion selective electrode can also detect ions that a. can form precipitate with (C10H21O)2PO2 b. can form precipitate with Ca+2 c. can form complex with (C10H21O)2PO2 d. can form complex with Ca+2

2 Does anyone know how to dissolve the alginate in the microencapsulates? I am trying to encapsulate probiotics to add them to coffee in the form of microencapsulates, the problem is that the alginate does not dissolve and remains a very gelatinous consistency, how can I dissolve them or in what proportion should I add it. Besides EDTA and glycerol what else would work as a chelating agent since I also want to lyophilize them.
