WebbPhage particles were disrupted and the DNAs were fixed on filters (50,000 plaques per 8.4 x 8.4 cm filter). The air-dried filters were baked at 80'C for 1 hr and then subjected to proteinase K digestion [50 ,ug ofproteinase 'K per ml of buffer solution containing 0.1 M Tris HCl (pH 8.0), 0.15 M NaCl, 10 mM EDTA, and 0.2% NaDodSO4] for 30 min at 550C. WebbA solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base Weak acids/bases only partially dissociate in water. Finding the pH of a weak acid is a bit more complicated.
