The Theory of Acids and Bases
نویسنده
چکیده
The Water or Arrhenius Theory was widely accepted up to the early years of this century . It defines an acid as a hydrogen compound ionizing in water to give hydrogen ions, and a base as a hy<iToxyl compound which gives hydroxide ions in water. The neutralization reaction between an acid and a base produces a salt and water only: HA(ac id) + BOH(base) ""' BA(salt) + H 20(water) and the salts so formed may be classified into four main groups, viz.: (i) those derived from strong acids and strong bases ; (ii) those derived from weak acids and strong bases ; (iii) those derived from strong acids and weak bases;

New characterizations of fusion bases and Riesz fusion bases in Hilbert spaces
In this paper we investigate a new notion of bases in Hilbert spaces and similar to fusion frame theory we introduce fusion bases theory in Hilbert spaces. We also introduce a new denition of fusion dual sequence associated with a fusion basis and show that the operators of a fusion dual sequence are continuous projections. Next we dene the fusion biorthogonal sequence, Bessel fusion basis, Hil...
متن کاملResponsibility of Cosmetic Surgeons with Three Bases of Fault Statistics, Fault Theory and Risk Theory
The present research, which is descriptive-analytic, answers the basic question of which basis of responsibility is more consistent with the doctors of the surgeon (pure) and closer to justice ?! Among the various types of foundations of doctors' responsibility, in the more or less complicated process of treatment and treatment, the underlying assumption of fault is more closely aligned between...
متن کاملOperator-valued bases on Hilbert spaces
In this paper we develop a natural generalization of Schauder basis theory, we term operator-valued basis or simply ov-basis theory, using operator-algebraic methods. We prove several results for ov-basis concerning duality, orthogonality, biorthogonality and minimality. We prove that the operators of a dual ov-basis are continuous. We also dene the concepts of Bessel, Hilbert ov-basis and obta...
متن کاملOne Pot Synthesis of Alpha-Aminonitrile and Alpha-Amino Acid From Schiff Bases
Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.

Background: Today, commercial activities have become more complex and complex than in the past, and for this reason, it has become a category with more sensitivities. One of the dimensions of trade sensitivity in the present age is related to the type of allocation of trade interests and beneficiaries of these interests. In the past, only family businesses and businesses benefited from the bene...
متن کاملGlobal optimization of mixed-integer polynomial programming problems: A new method based on Grobner Bases theory
Mixed-integer polynomial programming (MIPP) problems are one class of mixed-integer nonlinear programming (MINLP) problems where objective function and constraints are restricted to the polynomial functions. Although the MINLP problem is NP-hard, in special cases such as MIPP problems, an efficient algorithm can be extended to solve it. In this research, we propose an algorit...
