- The Ksp values of two solid carbonates, A2CO3 and BCO3, were determined by preparing 250.0-mL saturated aqueous solutions of both solids and then determining the concentration of carbonate by titrating it with 0.01023 M HCl up to methyl orange endpoint. Solutions of A2CO3 and BCO3 required 6.184 mL and 3.456 mL of the titrant, respectively.d. Instead of distilled water, 250.0 mL of 0.10 M ANO3 was used to prepare a saturatedsolution of A2CO3 while 250.0 mL of 0.10 M B(NO3)2 was used for BCO3. Which will have a higher solubility?The UV–visible spectrum of GLB-1 is given in Figure 2. i.What colour(s) will the deoxy and oxy forms of GLB-1 be?

- Mass of maleic anhydride used: 5.1296 gram Volume of furan used: 3.25 ml Volume of THF used: approx. 16ml The reaction mixture was allowed to stand undisturbed for one week, whereupon, gem-like, colorless to white, prismatic crystals were isolated from the solvent matrix and allowed to air dry. When dry, the mass of the crystals was determined to be: 4.6732 gram. One small crystal was selected and ground to a fine powder for melting point measurement. The powder was observed to melt at 117 – 118 deg C. About 1ml of a saturated solution of product dissolved in DMSO-d6 was prepared and placed in an NMR tube. Subsequently, proton, carbon-13 and DEPT NMR spectra were acquired. Analysis Write the reaction using structural formulas.
