2. Boric acid - Wikipedia

   en.wikipedia.org/wiki/Boric_acid

   Boric acid is a weak acid, with pK a (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of 9.24 in pure water at 25 °C. But apparent pK a is substantially lower in swimming pool or ocean waters because of interactions with various other molecules in solution. It will be around 9.0 in a ...

3. Tetraborate - Wikipedia

   en.wikipedia.org/wiki/Tetraborate

   The hydrated tetraborate anion occurs in the mineral borax (sodium tetraborate octahydrate) with the formula Na 2 [B 4 O 5 (OH) 4]·8H 2 O. The borax chemical formula is also commonly written in a more compact notation as Na 2 B 4 O 7 ·10H 2 O. Sodium borate can be obtained in high purity and so can be used to make a standard solution in ...

4. Aqion - Wikipedia

   en.wikipedia.org/wiki/Aqion

   Aqion is a hydrochemistry software tool. It bridges the gap between scientific software (such like PhreeqC [1]) and the calculation/handling of "simple" water-related tasks in daily routine practice.

5. Borax - Wikipedia

   en.wikipedia.org/wiki/Borax

   Borax (also referred to as sodium borate, tincal (/ ˈ t ɪ ŋ k əl /) and tincar (/ ˈ t ɪ ŋ k ər /)) is a salt (ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na 2 H 20 B 4 O 17.

6. Borate - Wikipedia

   en.wikipedia.org/wiki/Borate

   Polymeric boron oxoanions are formed in aqueous solution of boric acid at pH 7–10 if the boron concentration is higher than about 0.025 mol/L. The best known of these is the tetraborate ion [B 4 O 7] 2−, found in the mineral borax: 4 [B(OH) 4] − + 2 H + ⇌ [B 4 O 5 (OH) 4] 2− + 7 H 2 O

7. Buffer solution - Wikipedia

   en.wikipedia.org/wiki/Buffer_solution

   The smaller the difference, the more the overlap. In the case of citric acid, the overlap is extensive and solutions of citric acid are buffered over the whole range of pH 2.5 to 7.5. Calculation of the pH with a polyprotic acid requires a speciation calculation to be performed. In the case of citric acid, this entails the solution of the two ...
