Counterion of strong bases

WebIn chemistry, an alkoxide is the conjugate base of an alcohol and therefore consists of an organic group bonded to a negatively charged oxygen atom. They are written as RO−, where R is the organic substituent. Alkoxides are strong bases and, when R is not bulky, good nucleophiles and good ligands. Alkoxides, although generally not stable in ... WebVideo transcript. One way to make ethers is to use the Williamson ether synthesis, which is where you start with an alcohol, and you add a strong base to deprotonate the alcohol. Once you deprotonate the alcohol, you add an alkyl halide, and primary alkyl halides work the best. We'll talk about why in a minute.

WebThe counterion of the anion exchanger usually is a weakly binding one–for example, Cl-–that can be replaced by anions with higher affinity, such as negatively charged amino acids on the protein surface. ... Strong base anion exchangers are known only as polymerization products. Those with quaternary ammonium groups are the most common ... WebThe concentration of OH⁻ in a strong base solution can therefore be determined from the initial concentration of the base and the stoichiometry of the dissolution. For example, the strong base Ba (OH)₂ dissociates to give two OH⁻ ions per formula unit, so a 0.1 M Ba (OH)₂ solution has an OH⁻ concentration of 0.2 M.

A strong base yields 100% (or very nearly so) of OH − and HB + when it reacts with water; Figure 14.3.1 lists several strong bases. WebIt is the main component of table salt, used in cooking. Sodium chloride contains sodium ions, each with a +1 charge, and chloride ions, each with a -1 charge. Overall, the compound has no charge, because the positive sodiums balance out the charge on the negative chlorides, and vice versa. (3.2.1) N a + + C l − = N a C l (no overall charge) law butler
