The phrase "acidity test" is correct and usable in written English.
It can be used in contexts related to chemistry, food science, or any field where measuring acidity is relevant.
Example: "Before we proceed with the fermentation process, we need to conduct an acidity test to ensure the pH levels are appropriate."
Alternatives: "pH test" or "acid test".
Moreover, the distribution of acid sites in IM-5 zeolites can be influenced by the appearance of secondary mesoporous structures; as shown in the acidity test (Fig. 4; Table 2), the acidic strength and density then change along with it.
"The trouble," says Ridgeway, "is that it's quite easy to clean up, say, an oil that doesn't quite pass the acidity test, and to do it without leaving any chemical markers.
Techniques of acidity test and NMR were introduced to verify the proposed mechanism.
It can be summarized from the acidity test that a majority of MoO3 migrated into the channels of zeolites and related to the strong Brønsted acid during the physical mixing process of MoO3.
The stability distinction of ZnL2 and ZnSt2, and the stable effect of the two systems after being combined with CaSt2, were investigated by the Congo red test, solution acidity test, and discoloration test.
Furthermore, the stability time of ZnL2 was 36 min in the solution acidity test, which was 2 times higher than that of ZnSt2, and the stability time was increased to 196 min after combining it with CaSt2, which was 8 times greater than that of the Ca/Zn stabilizer.
Follow the instructions that came with your acid testing kit to test the acidity of your must.
Use the acid blend in your kit until it reaches 65% Follow the instructions that came with your acid testing kit to test the acidity of your must.
The catalysts were characterized by FTIR, TGA, elemental analysis, UV vis and a Hammet acidity function test.
Zeolites differing in structure and acidity were tested in liquid phase acylation of p-xylene.
The tunable acidities were tested by methanol dehydration to dimethyl ether (DME), and the dehydration activity of methanol over the catalysts shows a linear decrease with the increased Lewis/Brönsted ratio, while the selectivity of DME shows a linear increase with the enhanced Lewis/Brönsted ratio.
