:Most acidic salts of diprotic acids are solid ( e . g.
2.
Sulfuric acid is a diprotic acid and shows different properties depending upon its concentration.
3.
diprotic acid titrated with a strong base.
4.
For example, sulfuric acid ( H 2 SO 4 ) is a diprotic acid.
5.
For a diprotic acid, the hydrogen ion concentration can be found at the isoionic point using the following equation
6.
The dissociation processes of a diprotic acid does not happen all at once due to the two stages of dissociation having different Ka values.
7.
A buffer made by a diprotic acid and its conjugate base can be treated in the same way as a buffer made by a monoprotic acid.
8.
Most often, the carbonate system is plotted, where the polyprotic acid is carbonic acid ( a diprotic acid ), and the different species are carbonic acid, carbon dioxide, bicarbonate, and carbonate.
9.
A diprotic acid with two equivalent acidic sites, for example, if the interaction between the two sites were negligible, would be more acidic than a similar monoprotic acid by 0.3 pKa units just for statistical reasons ( 0.3 ~ log 2 ).
10.
The five-membered ring also possesses a keto group ( in the 8 position ), flanked by two secondary amino groups ( in the 7 and 9 positions ), and deprotonation of one of these at high pH could explain the p " K " 2 and behavior as a diprotic acid.
