Meanings of higher ph in inglês

At higher pH, bromoxynil was inert even at high concentrations.

At higher pH (7.4), the release rates increased with reaction solvent content.

They differ in their pH dependences: the activity of IIa increases at higher pH, whereas the IIb shows no or a slightly opposite pH dependence.

At a higher pH (4.8 and 5.4), L. acidophilus in higher quantities did not compete for binding sites occupied by G. vaginalis and M. curtisii.
