Finally, elemental sulfur is also used as a soil amendment to reduce soil pH when values are initially in excess of 8.5. Elemental sulfur is oxidized byautotrophic bacteriasuch asThiobacillus thiooxidans, resulting in the production ofsulfuric acidand a concomitant soil pH decrease (see alsoChapter...
Acidity in water bodies with pH of about 4 up to 8.3 is caused by carbon dioxide and dissolved humic substances. Waters with pH <4.0 usually contain sulfuric acid or possibly another strong acid, but they still contain carbon dioxide and possibly humic compounds. Low pH is associated with low...
Uptake of HCl molecules by aqueous sulfuric acid droplets as a function of acid concentration The droplets are switched on and off while the density of the species is continuously monitored by infrared absorption. From the on-off signal a ... LR Watson,Van Doren, Jane M.,P Davidovits,......
(2) dried clays and cracking catalysts are still strongly acid after they have been "neutralized" with aqueous sodium hydroxide solution; (3) unused silica-alumina catalysts appear to be at least as strongly acid as 90% sulfuric acid; (4) silica-magnesia catalysts are weaker acids than silica...
Acidity in soil andfresh wateris often increased by ‘acid rain’ the deposition of sulfuric andnitric acidsin part caused by human-made chemical pollution. The effects of acid rain on microbial processes such as decomposition are generally seen at pH levels a unit lower (pH 5) than those wh...
