Sentence examples for ph approx from inspiring English sources

It seems rather unlikely that the pH value of seepage water in typical agricultural soils reaches pH values low enough to dissolve CdS taking into consideration that the artificial rain water used in this experiment has a higher acidity (pH approx. 3) than natural rain water to simulate a worst case situation and that the sandy soil sample has quite a small buffering capacity for acids.
