a bronstead net equation shows a molecule of the acid reacting with H2O to show which is donating the H ion. the acid will donate, and the base will accept it. a. since lithium hydrogen phosphate has a ph of 9.70, it will be receiving a H, as it is basic. Li2HPO4 + 2H2O = H3PO4 + 2LiHO because H2O lost the H atom and Li2HPO4 gained it, showing which is the acid and which is the base. b. LiHSO4 + H2O = LiOH + H2SO4 the same is true with this one, the LiHSO4 gained a H atom and water lost one. c. H2C4H4O5 + H2O = HC4H4O5 + H3O the maltic acid is donating a H atom to the water, showing us which is the acid and base. d.HC3H5O3 + H2O = C3H5O3 + H3O the lactic acid is donating a H atom, and the water is accepting; the lactic acid is the acid, and H2O is the base. I hope this helped.
