The phrase "acidic materials" is correct and usable in written English.
It can be used when referring to substances that have a low pH or are capable of donating protons in a chemical reaction.
Example: "The laboratory requires proper handling and storage of acidic materials to ensure safety and compliance with regulations."
Alternatives: "acidic substances" or "acidic compounds".
Acidic materials (zeolites, supported acids) were screened for the alkylation of 3-methylthiophene (3MT) with 2-methyl-2-butene (2M2B), used as model reaction.
This maybe due to the reduction in the Brϕnsted acidity of the support, highly Brϕnsted acidic materials are well known to catalyse the conversion of EtOH to ethene and diethyl ether.
This easy of use direct method is highly flexible and covers the whole acidity scale from weakly acidic to strongly acidic materials.
Addition of weakly acidic materials also preserved fluorescence.
If acidic materials are to be managed by blending, the offsetting alkaline strata should also be identified.
Many pasture plant species prefer soil pH in the 6.0 to 7.0 range, although slightly more acidic materials (>5.5) can be used if the mine soils are limed.
Another acidic material tested is acetic acid which was discussed by some authors as well.
There, Hungarian scientists had sought to neutralize the effect of the caustic alkaline substance by adding acidic material.
In particular, it is worth mentioning that batteries, with their acidic material, may result in significant corrosive damage to the oesophagus if not promptly removed [18].
The use of an acidic material to prevent the SO2 effect and containing an oxidising function seems to be a very good alternative to improve the efficiency of the SCR process.
K.K. Sasidharan Pillai, a senior scientific assistant in the Indian Meteorological Department, proposed dust and acidic material from an eruption of Mayon Volcano in the Philippines as an explanation for the coloured rain and the "burnt" leaves.
