SUMMARY

Oxalic acid (H2C2O4) can donate two hydronium ions (H3O+) when dissolved in water, demonstrating its behavior as a Brønsted-Lowry acid. The balanced dissociation equations are: H2C2O4 + H2O → H3O+ + HC2O4- for the first ion, and HC2O4- + H2O → H3O+ + C2O4-2 for the second ion. This discussion clarifies the acid-base reaction mechanism involving oxalic acid and water.

Homework Statement



Oxalic acid, H2C2O4, which is found in certain pants, can provide two hydronium ions in water. Write balanced equations to show how oxalic acid can supply one and then a second H3O+ ion.

Homework Equations



There's not really an equation, and if there is please don't make me feel stupid.

The Attempt at a Solution



I don't really even know how to start.

You must try something. Oxalic acid reacts with water, how? Water is an acid or a base, depending on what is present with it. Oxalic acid will behave as an acid. How does the H3O+1, hydronium ion form?
 
Do you know how to write dissociation equation for any acid?
 
I think I figured it out:

H2C2O4 + H2O -> H3O+ + HC2O4-

HC2O4- + H2O -> H3O+ + C2O4-2
 
Good.
 
In which pants do you find oxalic acid?

Are you sure you asked what you wanted to ask?
