Is H2CO3 acid or a base? H2CO3 isa weak acidthat dissociates into a proton (H+ cation) and a bicarbonate ion (HCO3- anion). This compound only partly dissociates in aqueous solutions. Furthermore, the conjugate base of carbonic acid, which is the bicarbonate ion, is a relatively good...
Buffers A buffer is a solution that resists changes in pH. The pH of a buffer changes very little when small amounts of a strong acid or strong base are added to the buffer. A buffer consists of approximately equal amounts of a conjugate weak acid/weak base pair in equilibrium with each...
True or false? The pH of a strong acid will always be less than that of a weak acid. True or false? The pH of a buffer is close to the pKa of the weak acid from which it is made. True or false? A buffer system is composed of a weak acid and ...

Describe the following as being a Bronsted acid, base, or both: a) H2CO3 b) HCO3-1 c) CO3-2 What is the formula for hydrosulfuric acid? What is the Lewis structure for CO3? How does the hydronium ion form? What is the conjugate base of H3PO4? What is a binary ionic compound...
We know that conjugate acid is a compound formed when a base accepts a proton. Here $C{O_3}^{2 - }$ accepts ${H^ + }$ from water and forms $HC{O_3}^ - $ So we can say that $HC{O_3}^ - $ is the conjugate acid as the carbonate ion cannot b...
In which one of the following pairs is the 2nd substance a stronger acid than the 1st? A. HCL CH3COOH B. H2PO4- H3PO4 C. H2SO4 H2CO3 D. H20 OH- Could you tell me which one is is stronger than the 1st and why? Cheers Scott...
