4) are produced by alkylation of organophosphines. [3] For example, the reaction of triphenylphosphine with methyl bromide gives methyltriphenylphosphonium bromide: PPh 3 + CH 3 Br → [CH 3 PPh 3] + Br −. The methyl group in such phosphonium salts is mildly acidic, with a pK a estimated to be near 15: [5] [CH 3 PPh 3] + + base → CH 2 =PPh ...
The measurement of pH can become difficult at extremely acidic or alkaline conditions, such as below pH 2.5 (ca. 0.003 mol/dm 3 acid) or above pH 10.5 (above ca. 0.0003 mol/dm 3 alkaline). This is due to the breakdown of the Nernst equation in such conditions when using a glass electrode.
A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. [1] Hence, a pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +) in the ...

THPC can be synthesized with high yield by treating phosphine with formaldehyde in the presence of hydrochloric acid. [1]PH 3 + 4 H 2 C=O + HCl → [P(CH 2 OH) 4]Cl. The cation P(CH 2 OH) 4 + features four-coordinate phosphorus, as is typical for phosphonium salts.
