In and of themselves, pH indicators are usually weak acids or weak bases. The general reaction scheme of acidic pH indicators in aqueous solutions can be formulated as: HInd (aq) + H 2 O (l) ⇌ H 3 O + (aq) + Ind − (aq) where, "HInd" is the acidic form and "Ind −" is the conjugate base of the indicator. Vice versa for basic pH indicators ...

Diphenyl diselenide is the chemical compound with the formula (C 6 H 5) 2 Se 2, abbreviated Ph 2 Se 2. This yellow-coloured solid is the oxidized derivative of benzeneselenol. It is used as a source of the PhSe unit in organic synthesis .

The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2] The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. [3]
In 1930 the Navy ordered nine aircraft, designated the PH-1, which were fitted with more powerful engines and a partly enclosed cockpit for the pilots. [4] The Coast Guard later ordered seven PH-2 aircraft, similar to the PH-1 but with armament removed, and seven PH-3 units with armament reinstated and a fully enclosed cockpit for the pilots.
