Surface acidity and basicity of La2O3, LaOCl, and LaCl3 characterized by IR spectroscopy, TPD, and DFT calculations. J Phys Chem B 2004;108:15770e81.Manoilova O. V,Podkolzin S. G,Tope B. et al.Surface Acidity and Basicity of La2O3, LaOCl, and LaCl3 Characterized by IR...
If аH+ > аOH- the solution is acidic (pH < 7), if аH+ < аOH- the solution is alkaline (pH > 7). The pH value is an important characteristic of all aqueous solutions and natural water bodies (rivers, lakes, seas, oceans). The pH value along with the reduction-oxidation (...
Answer to: Rank these compounds in order of their acidity. (least acidic) ___ less than ___ less than ___ less than ___ (most acidic)...
Mo2C micro-size spheres terminated by Al3 doped MoO2 layer exhibit a notable performance of alkaline hydrogen evolution with a near-zero onset-potential, a low overpotential (40 mV) at a typical current density of 10 mA/cm2, and a small Tafel slope (45 mV/dec), as well as a long-ter...
The introduction of pH as an indicator of acid-base properties of aqueous solutions was founded on the ability of water to dissociate into ions according to the scheme H2O = H++OH−. In connection with this reaction and using the concept of ionic product of water, KW= aH++ aOH-(where...
Furthermore, an absolute gas-phase acidity scale is presented which is anchored to the gas-phase acidity value for acetone determined by Bartmess et al... JL Burkell,TD Fridgen,TB Mcmahon - 《International Journal of Mass Spectrometry》 被引量: 28发表: 2003年 Revision of the Gas-Phase Ac...

The surface acidity of Nb(OH)_5-modified zeolite was characterized by FT IR spectra of pyridine absorbed on the surface.Catalytic activity was determined by the catalytic removal of trace olefins from aromatic hydrocarbons.The results showed that the presence of niobium leads to redistribution of Br...
The overall reaction of lime with an acid soil can be expressed as (9.8)2Al-soil+3CaCO3+3H2O→3Ca-soil+2Al(OH)3+3CO2. One sees that the products are exchangeable Ca2+ and Al(OH)3. Assuming that all of the acidity was completely neutralized one would find that the soil pH would ...
