20.4 Amines and Amides – Chemistry

Amines are molecules that contain carbon-nitrogen bonds. The nitrogen atom in an amine has a lone pair of electrons and three bonds to other atoms, either carbon or hydrogen. Various nomenclatures are used to derive names for amines, but all involve the class-identifying suffix –ine as illustrated here for a few simple examples:. In some amines, the nitrogen atom replaces a carbon atom in an Get price

Coordination properties of Cu(II) and Ni(II) ions towards

The acetyl-TESHHK-amide peptide, modeling a part of the C-terminal tail of histone H2A, was found previously by us to undergo at pH 7. 4 a Ni(II)-assisted hydrolysis of the E-S peptide bond with formation of a stronger Ni(II) complex with the SHHK-amide product [Bal, W., et al. (1998) Chem. Res. Toxicol. 11, 1014-1023]. To further characterize the hydrolysis and test the resulting Ni(II Get price

Specific Conductance: Theoretical Considerations and

tions. Ions in solution are surrounded by a sphere of oppositely charged ions and water. When a potential field is imposed on a solution, the migration of the central ion distorts the cosphere of water and oppositely charged ions, and the cosphere itself seeks to move in the opposite direction.

samples, prepared to contain specific ions of interest, as well as unknown samples in order to test your ability to use the procedure to analyze a solution of unknown composition. In this way, you can observe first-hand how a particular ion behaves when a certain reagent is added and make comparisons with the behavior of your unknown sample. Get price

Benedict's Test

Aug 15, 2019Benedict's Test is used to test for simple carbohydrates. The Benedict's test identifies reducing sugars (monosaccharide's and some disaccharides), which have free ketone or aldehyde functional groups. Benedict's solution can be used to test for the presence of glucose in urine. Some sugars such as glucose are called reducing sugars because they are capable of transferring Get price

Ionic Electrolytes

When some substances are dissolved in water, they undergo either a physical or a chemical change that yields ions in solution. These substances constitute an important class of compounds called electrolytes.Substances that do not yield ions when dissolved are called nonelectrolytes.If the physical or chemical process that generates the ions is essentially efficient (all of the dissolved Get price

Identification of Unknown Anions in Solution

Reactions between specific chemicals are unique and can be used to identify various elements and compounds. In this lab, you are going to investigate the reactions of Chloride Ion [NaCl] HNO 3 and AgNO 3 Sulfate ion [Na Add 10 drops of silver nitrate solution to the test tube with the chloride ions. Gently flick the test Get price

Assessment of Learning: Table of Specification

Aug 15, 2012A Table of Specifications provides the teacher with evidence that a test has content validity, that it covers what should be covered. Designing a Table of Specifications Tables of Specification typically are designed based on the list of course objectives, the topics covered in class, the amount of time spent on those topics, textbook chapter Get price

Encoding specificity principle

The encoding specificity principle is the general principle that matching the encoding contexts of information at recall assists in the retrieval of episodic memories.It provides a framework for understanding how the conditions present while encoding information relate to memory and recall of that information.. It was introduced by Thomson and Tulving who suggested that contextual information Get price

Testing for Anions

The test for halogens, or halide ions, is to add silver nitrate to a solution. Often, nitric acid is added first as well. If there are chloride, bromide or iodide ions in the solution they will react with silver to form a precipitate. The different precipitates are summarized in the table below. Get price

What Do Electrolytes Do? Benefits, Chemistry Imbalance

Chloride is the major anion (negatively charged ion) found in the fluid outside of cells and in the blood. An anion is the negatively charged part of certain substances such as table salt (sodium chloride or NaCl) when dissolved in liquid. Chloride plays a role in helping the body maintain a normal balance of fluids. Get price

Why Does Iodine Turn Starch Blue? :: Education

Iodine Test. Using iodine to test for the presence of starch is a common experiment.
