analyte, weak acid titrant, strong base reaction during titration HC2 H3 O2 NaOH HC2 H3 O2 + NaOH ↔ NaC2 H3 O2 The extent of dissociation can also be described by dissociation constants symbolized as a Ka (for acids) and Kb (for bases). Since the Ka or Kb can be a very small or...
Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways including K_a or K_b, pK_a or pK_b, and perc ...

Dye diffusion process with base precursor salts of strong organic bases and weak organic acidsDye diffusion images can be produced by a rapid process in which a first sheet material which contains at least one light sensitive silver halide emulsion on a layer support and at least one color ...
In data from leukocytes of 80 controls22, there was only a weak correlation between the expression levels of CD69 and CASP-3 (R2 ¼ 0.13), suggesting that the high correlation observed at the protein level is either because of post transcriptional regulation, for example, epigenetic ...
