Therefore, these acids cannot dissociate completely into ions; they can only partially dissociate into the ions. Overview and Key Difference 2. What is Phosphoric Acid 3. What is Citric Acid 4.
Similarities — Phosphoric Acid and Citric Acid 5. Summary — Phosphoric Acid vs Citric Acid. Phosphoric acid is a weak mineral acid having the chemical formula H 3 PO 4. Moreover, it is an important phosphorous-containing compound from which the dihydrogen phosphate ion H 2 PO 4 — is derived. Therefore, ions in phosphoric acid are very important for plants because it is the major source of phosphorous.
The molar mass of phosphoric acid is There can be hydrated and anhydrous forms of this compound. Phosphoric acid appears as a white solid that is deliquescent and odorless. Moreover, phosphoric acid production has two pathways: wet process and thermal process. The wet process uses fluoroapetite phosphate rock for the production of this acid, along with concentrated sulfuric acid.
The chemical reaction is as follows:. Methods: Enamel samples of non-erupted human third molars were treated with acidic solutions of tartaric TA , malic MA , lactic LA , ascorbic AA , phosphoric PA and citric CA acids with a concentration that gave an equivalent sensorial acidic taste.
The acidic solutions were characterized by pH value and titratable acidity. Atomic force microscopy AFM based nanoindentation was used to study the nano mechanical properties and scanning electron microscopy SEM was used to study the morphology of the treated enamel samples and the untreated control areas, respectively. Results: The investigated acids fell into two groups. As I don't buy the chemical it is not my place to speculate, but it was certainly interesting to explore.
