Acid Base Equations questions?

(a) Write an equation for the reaction in which H2C6H7O5-(aq) acts as a base in H2O(l). (Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)

Answer 1

a) H2C6H7O5- (aq) + H20 (l) -> H3C6H7O5 (aq) + OH- (aq)

b) H2C6H7O5- (aq) + H20 (l) -> H(C6H7O5)2- (aq) + H3O+ (aq)

c) If H2C6H7O5- was a base, its conjugate acid would be H3C6H7O5
However, if it was an acid, its conjugate base would be H(C6H7O5)2-

Remember that acids lose an H+ ion to form conjugate bases and bases gain an H+ ion to form a conjugate acid.
