Derivatives of Carbonic Acid Carbonic acid (H 2 CO 3 ) is unstable and dissociates to CO 2 and H 2 O. The reaction is reversible so when CO 2 dissolves in water some H 2 CO 3 is formed. Carbonic acid is a weak acid, pK a (1) = 6.36. Solutions of carbonated water (including natural rainwater) are slightly acidic. HOCOH O = carbonic acid CO 2 + H 2 O

Derivatives of Carbonic Acid Many stable derivatives of carbonic acid are known: Monoderivatives of Carbonic Acid are Unstable C 2 H 5 O C OH O = CH 3 CH 2 OH + CO 2 H 2 N C OH O = NH 3 + CO 2 Cl C OH O = HCl + CO 2 Cl C Cl O = phosgene (carbonyl chloride) H 2 N C NH 2 O = urea (carbamide) C 2 H 5 O C OC 2 H 5 O = ethyl carbonate C 2 H 5 O C Cl O = ethyl chlorocarbonate H 2 N C OC 2 H 5 O = ethyl carbamate (a "urethane")

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
