Is methanol a weak acid
WitrynaA weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H +) in a solution. Weak acids have very small values for K a (and therefore higher values for pK a) compared to strong acids, which have very large K a values (and slightly negative pK a values). WitrynaAt pH 3.0, as percent methanol increases, the retention times of both phenol and benzoic acid decrease significantly. Because both solutes are polar, increasing mobile-phase polarity causes both to be retained less tightly.

WitrynaMethanol is very weak acid (e.g. its dissociation constant is very small), so its conjugated base is very strong.

Also the methanol can act as an oxidizer:
