WebWhat is the pH of 8 x 10^-8 M HCl? Expert Answer 91% (65 ratings) This is a solution of HCl. The solution is acidic. The ph must therefore be less than 7.00If you take HCl to dissociate completely , then [H+] = 8*10^-8MIf you apply the formula:pH = -log [H+]pH = -log 8*10^-8pH = 7.097This answer must be wrong becau … View the full answer WebThe release profiles of each drug from the drug–fiber complexes in pH 1.2 HCl solution and pH 6.8 phosphate buffer are shown in Figure 7. The rate of drug release from the fiber was determined by extrapolating the time when 50% ( t 50% ) and 80% ( t 80% ) of the drug in the fiber was released into the dissolution medium ( Table 5 ).
