What is Ka of citric acid?

0.74. 3.2 × 10 −7. 6.49. Citric acid.

Does Ka change with pH?

Ka is a better measure of the strength of an acid than pH because adding water to an acid solution doesn’t change its acid equilibrium constant, but does alter the H+ ion concentration and pH.

Which is the correct formula for pyrophosphoric acid?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).?) Pyrophosphoric acid, also known as diphosphoric acid, is the inorganic compound with the formula H 4 P 2 O 7 or, more descriptively, [ (HO) 2 P (O)] 2 O. Colorless and odorless, it is soluble in water, diethyl ether, and ethyl alcohol.

What is the structure of pyrophosphate anion h4o7p2?

The pyrophosphate anion has the structure P2O74-, and is an acid anhydride of phosphate. It is unstable in aqueous solution and rapidly hydrolyzes into inorganic phosphate.

What happens to pyrophosphoric acid when it melts?

When molten, pyrophosphoric acid rapidly forms an equilibrium mixture of phosphoric acid, pyrophosphoric acid and polyphosphoric acids. The percentage by weight of pyrophosphoric acid is around 40% and it is difficult to recrystallise from the melt.

What is the chemical formula for pyruvic acid?

Pyruvic acid HC3H3O3 1.4×10–4 Quinolinium ion HC9H7N+ 1.6×10–5 Selenous acid H2SeO3 2.3×10–3 Succinic acid H2C4H4O4 6.2×10–5
