The basicity of an endodontic material can be expressed in terms of two different aspects: (1) the highest pH value obtainable and (2) acid neutralizing capacity.
Stabilised free radicals present in the basal planes may also contribute to basicity (Montes-Moran et al.
Therefore, the variation of the basicity of the slags is based on the evaluation of the static state of the solidified melt.
de Nice-Sophia Antipolis-CNRS, France) should allow for the judicious choices of a few reference Lewis acids in order to construct Lewis basicity scales that cane be used as a general guide to basicity.
Among heterogeneous catalysts, CaO is of interest due to its high basicity, low solubility, low price, and long lifetime (Liu et al.
It has excellent compatibility with polyolefins and offers low basicity so there is less chance of chemical interaction.
The aqueous phase pH was measured using a digital pH probe (Orion Research, model 701A) and was adjusted to a value of 9 by addition of NaOH such that it's basicity matches commercial process waters.
Such studies have usually been limited to a small number of similar bases, and limited relationships have been established between experimental and theoretically calculated cation basicity (or affinity) values.
The steric shielding of the free electron pair in the nitrogen atom of the amine and its reduced basicity enhance its effectiveness as a stabilizer.
A volatile alkali, such as ammonium hydroxide, is added to perms which dissipates during the process to reduce the basicity of the solution.
Similar molecules and ions could have potential applications in areas such as catalysis and the fabrication of magnetic switches; in addition, they are expected to exhibit interesting gas-phase acidity and/or basicity properties.
This ratio, which is the ratio of basic oxide to an acidic oxide, determines the basicity of the glass and because the reaction between glass and liquid is an acid base one, an increase in the basicity of the glass will increase the rate of the setting reaction.
