  2. Brønsted–Lowry acid–base theory - Wikipedia

    en.wikipedia.org/wiki/Brønsted–Lowry_acid...

    A solution of B(OH) 3 is acidic because hydrogen ions are given off in this reaction. There is strong evidence that dilute aqueous solutions of ammonia contain minute amounts of the ammonium ion + + + and that, when dissolved in water, ammonia functions as a Lewis base. [18]

  3. Brønsted catalysis equation - Wikipedia

    en.wikipedia.org/wiki/Brønsted_catalysis_equation

    A plot of the common logarithm of the reaction rate constant k versus the logarithm of the ionization constant K a for a series of acids (for example a group of substituted phenols or carboxylic acids) gives a straight line with slope α and intercept C. The Brønsted equation is a free-energy relationship.

  4. Conjugate (acid-base theory) - Wikipedia

    en.wikipedia.org/wiki/Conjugate_(acid-base_theory)

    Ringer's lactate solution is an example where the conjugate base of an organic acid, lactic acid, CH 3 CH(OH)CO − 2 is combined with sodium, calcium and potassium cations and chloride anions in distilled water [ 4 ] which together form a fluid which is isotonic in relation to human blood and is used for fluid resuscitation after blood loss ...

  5. Extraneous and missing solutions - Wikipedia

    en.wikipedia.org/wiki/Extraneous_and_missing...

    Because of this, often, the only simple effective way to deal with multiplication by expressions involving variables is to substitute each of the solutions obtained into the original equation and confirm that this yields a valid equation. After discarding solutions that yield an invalid equation, we will have the correct set of solutions.

  6. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    The equation is −ΔH = E A E B + C A C B + W. The W term represents a constant energy contribution for acid–base reaction such as the cleavage of a dimeric acid or base. The equation predicts reversal of acids and base strengths. The graphical presentations of the equation show that there is no single order of Lewis base strengths or Lewis ...

    An example of a nonlinear delay differential equation; applications in number theory, distribution of primes, and control theory [5] [6] [7] Chrystal's equation: 1 + + + = Generalization of Clairaut's equation with a singular solution [8] Clairaut's equation: 1

  8. MUSCL scheme - Wikipedia

    en.wikipedia.org/wiki/MUSCL_scheme

    The diagram opposite shows a 3rd order solution to G A Sod's shock tube problem (Sod, 1978) using the above high resolution Kurganov and Tadmor Central Scheme (KT) but with parabolic reconstruction and van Albada limiter. This again illustrates the effectiveness of the MUSCL approach to solving the Euler equations.

    [3] In 1929, Brønsted was a visiting professor at Yale University. [4] His research gained worldwide recognition, resulting in four Nobel Prize nominations, a gold H. C. Ørsted Medal and being appointed as a fellow of the Royal Society and a member of the National Academy of Sciences. [1] [5]
