The phrase "acidity strength" is correct and usable in written English.
It can be used in contexts related to chemistry or food science, particularly when discussing the intensity or level of acidity in a substance.
Example: "The acidity strength of the vinegar was much higher than that of the lemon juice, making it a more potent ingredient for the salad dressing."
Alternatives: "level of acidity" or "acidity level".
The Hammett acidity function (H0) can effectively express the acidity strength of an acid in organic solvents.
Brønsted acidity is a key factor controlling catalytic performance of zeolites in many technological processes, and hence the need to find a reliable means for measuring acidity strength.
The introduction of phosphoric groups, with higher acidity strength, improved the selectivity to h-GTBE, and glycerol triether was detected in low amounts.
Ionic additives principally affected the intermediate acidity strength (NH3 desorption temperature range 473 673 K), which varied from 1.1 (Mg2+) to 3.2 (SO42−) μmol.m−2.
The thermodynamic stability and the expected acidity strength of Lewis/Brønsted superacids (considered here as consisting of superhalogen anions and the additional protons) are examined for the systems containing selected alkali metals, alkali earth metals, metalloids and non-metals.
Comparing the kinetic models of deactivation for two catalysts with different acidity strength distributions, the need for a kinetic model of selective deactivation is attributed to the heterogeneous nature of the acidic structure of the catalyst.
Studies indicate that the distribution of products obtained by zeolitic methanol conversion strongly depends on the acidity (acid strength and number of acid sites) and channel structure of zeolite [1].
This finding is interesting for the optimized design of catalysts with different acidity strengths to cater for various applications.
The total acidity and acid strength distribution were determined by NH3-TPD.
The comparisons of the acidity in dealuminated HZSM-5 by traditionally steaming and improved methods indicated that the latter was more effective in decreasing the acidity and weakening acid strength, and more environmentally benign and timesaving.
From these results, one can speculate that the hydrogenolysis activity of Ru/CeO2 is strongly dependent on the specific surface area, acid strength, total acidity, and metal support interaction.
