### 6A.4

Write the chemical equations for the proton transfer equilibria of the following bases in aqueous solution and identify the
conjugate acid–base pairs in each case: CO(NH2)2, urea
I am having trouble writing out the chemical equation for urea and water. How does urea lose an H?

Urea is actually a base, and it reacts with H2O to produce NH3 and CO2. The two H+ come from the H2O and bond to the NH2 groups, and the $O^{2-}$ bonds to the remaining C=O atoms.
