A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct. A Lewis base , then, is any species that has a filled orbital containing an electron pair which is not involved in bonding but may form a dative bond with a Lewis acid to form a Lewis adduct. For example, NH 3 is a Lewis base, because it can donate its lone pair of electrons.

Alcohol Oxidation: “Strong” and “Weak” Oxidants

Weak oxidants will only oxidize primary alcohols to aldehydes. If you think back to Gen Chem and transition metal oxidation states, this would correspond to an increase in oxidation state ]. We end up with a ketone! Eye of newt, wing of bat, powdered unicorn horn — no matter how powerful, none of them are able to oxidize our tertiary alcohol. Why is that? We would have to break a C-C bond in order for an oxidation to occur, and none of these reagents are competent to do this [for a clue as to why, see the next post]. Yes — it would be an ester [shown in grey].

You can represent the extent to which your acid dissociates -- and thus changes the solution's pH -- using its "pKa" value, and you can calculate this value using data from your titration experiment. As in the picture below, the titration curve of a weak acid has a characteristic shape. To calculate the acid dissociation constant pK a , one must find the volume at the half-equivalence point, that is where half the amount of titrant has been added to form the next compound here, sodium hydrogen oxalate, then disodium oxalate. This volume represents a stoichiometric excess of titrant, and a reaction solution containing both the titration product, acetate ion, and the excess strong titrant. The procedure is illustrated in the following subsection and Example How to Calculate pH from pKa? At the point when the example solution had a pH of 5.

An ICE I nitial, C hange, E quilibrium table is simple matrix formalism that used to simplify the calculations in reversible equilibrium reactions e. ICE tables are composed of the concentrations of molecules in solution in different stages of a reaction, and are usually used to calculate the K, or equilibrium constant expression, of a reaction in some instances, K may be given, and one or more of the concentrations in the table will be the unknown to be solved for. ICE tables automatically set up and organize the variables and constants needed when calculating the unknown. A sample consisting of 0. The equilibrium constant expression is expressed as products over reactants, each raised to the power of their respective stoichiometric coefficients:. The equilibrium concentrations of Y and Z are unknown, but they can be calculated using the ICE table.

Titration curves are obtained when the pH of given volume of a sample solution varies after successive addition of acid or alkali. The curves are usually plots of pH against the volume of titrant added or more correctly against the number of equivalents added per mole of the sample. This curve empirically defines several characteristics. Amino Acids are weak Polyprotic Acids. They are present as zwitter ions at neutral pH and are amphoteric molecules that can be titrated with both acid and alkali. The strong positive charge on the amino group induces a tendency for the carboxylic acid group to lose a proton, so amino acids are considered to be strong acids.

Несмотря на свой внушительный вид, дешифровальное чудовище отнюдь не было островом в океане. Хотя криптографы были убеждены, что система фильтров Сквозь строй предназначалась исключительно для защиты этого криптографического декодирующего шедевра, сотрудники лаборатории систем безопасности знали правду. Фильтры служили куда более высокой цели - защите главной базы данных АНБ. Чатрукьяну была известна история ее создания. Несмотря на все предпринятые в конце 1970-х годов усилия министерства обороны сохранить Интернет для себя, этот инструмент оказался настолько соблазнительным, что не мог не привлечь к себе внимания всего общества.

 Она девушка Эдуардо, болван. Только тронь ее, и он тебя прикончит. ГЛАВА 56 Мидж Милкен в сердцах выскочила из своего кабинета и уединилась в комнате для заседаний, которая располагалась точно напротив. Кроме тридцати футов ого стола красного дерева с буквами АНБ в центре столешницы, выложенной из черных пластинок вишневого и орехового дерева, комнату украшали три акварели Мариона Пайка, ваза с листьями папоротника, мраморная барная стойка и, разумеется, бачок для охлаждения воды фирмы Спарклетс.
