The phrase "acidic material" is correct and usable in written English.
It can be used in contexts related to chemistry, environmental science, or any discussion involving substances with a low pH.
Example: "The acidic material in the solution can cause corrosion to metal surfaces if not handled properly."
Alternatives: "sour substance" or "low pH material".
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 addition to retaining water, this acidic material inhibits the growth of certain pathogenic fungi such as damping off, that attacks young seedlings.
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.
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].
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.
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.
The MRL Archives present the special challenge of fragile acidic materials.
The whole system was validated by using zeolite Y, H-ZSM-5, and H-Mordenite as acidic materials and amorphous silica as nonacidic material.
