WebAns: Alkali metals form alkali (base) in contact with water, and they form metal oxides when water reacts. Alkali metal oxides are also bases and when dissolved in water, they form an alkaline solution. During reaction with water, Group 2 metals also form bases and their oxides are basic and found in the earth’s crust. 3. NaH is a base of wide scope and utility in organic chemistry. As a superbase, it is capable of deprotonating a range of even weak Brønsted acids to give the corresponding sodium derivatives. Typical "easy" substrates contain O-H, N-H, S-H bonds, including alcohols, phenols, pyrazoles, and thiols. NaH notably deprotonates carbon acids (i.e., C-H bonds) such as 1,3-dicarbonyls such as malon…

It is a non-flammable and powerful oxidizer. Summary. Perchloric acid is an inorganic or mineral acid that appears as a colorless liquid and is generally odorless in nature. WebAll data given in the figures apply to dilute aqueous solutions at ambient temperature. For bases, the pka value is given for the conjugate bases BH+ and BH22+. BH+ = B + H+. The pKb for a base may be calculated from the pKa value of its conjugate acid: pKw = pKa + pKb. At 25°C the pKw is 14 and. pKb = 14 - pKa. Web33 rijen · 1.
