triprotic and diprotic acids (1 Viewer)

[yorkstanham]

Hey, i have got no idea how to do these questions

Tartacid is diprotic while cirtic acid is triprotic. Write equations for the stepwise dissociation of the acids.

a) Citric acid (H<SUB>3</SUB>C<SUB>6</SUB>H<SUB>5</SUB>O<SUB>7</SUB>)
<SUB>
</SUB>b) Tartaric acid (H<SUB>2</SUB>C<SUB>4</SUB>H<SUB>4</SUB>O<SUB>6</SUB>)

Thanks

H₃C₆H₅O_{7+H2O--> H30+ +}C₆H7O<sub>7

C6H707+H20---> C6H6O7 2- + H30+

C6h6O7 + H20 ---> C6H5O7 +H30+



Same process for the other one but, it onle inoises twice, as it is diprotic.

H₃C₆H₅O_{7+H2O<=> H30+ +}C₆H7O<sub>7

C6H707+H20 <=> C6H6O7 2- + H30+

C6h6O7 + H20 <=> C6H5O7 +H30+

What he said was right, but remember to replace the full arrows with reversible arrows. Citric acid is a weak acid, and hence only ionises partially
