Description
Hydroxide is an anion with the chemical formula OH?. It is a fundamental component in various chemical reactions and processes, playing a crucial role in neutralizing acids, forming salts, and participating in ion exchange mechanisms.
Uses
Used in Water Treatment:
Hydroxide is used as a neutralizing agent for eliminating acidity in water. The expression is: Hydroxide is used as a neutralizing agent for [removing excess hydrogen ions and reducing acidity in water].
Used in Anion Exchange Resins:
Hydroxide is used as a key component in anion exchange resins, which are employed in various industrial applications for removing unwanted anions from solutions. The expression is: Hydroxide is used as a functional group in anion exchange resins for [facilitating ion exchange and removing targeted anions].
Used in Salt Splitting Applications:
In the salt splitting process, hydroxide ions are released by the resin as anions are adsorbed from the liquid phase, leading to the formation of a salt form of the resin. The expression is: Hydroxide is used as a reactant in salt splitting applications for [converting the resin to a salt form and facilitating the exchange of anions].
Used in Regeneration of Anion Exchange Resins:
Hydroxide is used to restore the anion exchange resins to their original OH? form, typically using a 4% solution of NaOH. The expression is: Hydroxide is used as a regenerating agent for anion exchange resins for [restoring the resin to its original form and maintaining its functionality].
Used in Selective Anion Removal:
Salt forms of strong base anion exchange resins are used to remove other anions for which the resin has greater selectivity. The expression is: Hydroxide is used as a selective agent in anion exchange resins for [removing specific anions based on the resin's selectivity].
Check Digit Verification of cas no
The CAS Registry Mumber 14280-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,8 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 14280-30:
(7*1)+(6*4)+(5*2)+(4*8)+(3*0)+(2*3)+(1*0)=79
79 % 10 = 9
So 14280-30-9 is a valid CAS Registry Number.

Cobalt porphyrin catalyzed reduction of CO2. Radiation chemical, photochemical, and electrochemical studies

Several cobalt porphyrins (CoP) have been reduced by radiation chemical, photochemical, and electrochemical methods, in aqueous and organic solvents. In aqueous solutions, the CoIP state is stable at high pH but is shorter lived in neutral and acidic solutions. Stable CoIP is also observed in organic solvents and is unreactive toward CO2. One-electron reduction of CoIP leads to formation of a species that is observed as a transient intermediate by pulse radiolysis in aqueous solutions and as a stable product following reduction by Na in tetrahydrofuran solutions. The spectrum of this species is not the characteristic spectrum of a metalloporphyrin π-radical anion and is ascribed to Co0P. This species binds and reduces CO2. Catalytic formation of CO and HCO2- is confirmed by photochemical experiments in acetonitrile solutions containing triethylamine as a reductive quencher. Catalytic reduction of CO2 is also confirmed by cyclic voltammetry in acetonitrile and butyronitrile solutions and is shown to occur at the potential at which CoIP is reduced to Co0P. As compared with CoTPP, fluorinated derivatives are reduced, and catalyze CO2 reduction, at less negative potentials.
