White vinegar is a 5.0% by mass solution of acetic acid in water. If the density of white vinegar is 1.007 g/cm3, what is the pH? The ionization constant of lactic acid, CH3CH(OH)CO2H, an acid found in the blood after strenuous exercise, is 1.36 × 10−4. If 20.0 g of lacti...
A mass range of m=z 100–1000 was covered, and data were collected in the negative ion mode (ESI). i) L-FDAA derivatives of the common amino acids: the column was maintained at 40 C. CH3CN-H2O contain- ing 0.3% AcOH was used as the mobile phase with linear gradient elution (...
