WebIt is both the conjugate base of carbonic acid H 2CO 3; and the conjugate acid of CO2− 3, the carbonate ion, as shown by these equilibrium reactions: CO2− 3 + 2 H 2 O ⇌ HCO− 3 + H 2 O + OH − ⇌ H 2 CO 3 + 2 OH − H 2 CO 3 + 2 H 2 O ⇌ HCO− 3 + H 3 O + + H 2 O ⇌ CO2− 3 + 2 H 3 O +.

"Hypothetical"acid of carbon dioxide and water Webhco3-是碱性。由于碳酸氢根的水解（产生OH-）程度大于电离（产生H+）程度，因此其水溶液呈弱碱性。酸根离子的水解程度较大，碳酸氢根结合的盐大部分是可溶性盐，而碳酸根离子结合的盐很多是不可溶的，碳酸氢根可以和氢氧根结合生成碳酸根和水。 food grade double sided tape

It has one more H atom and one more + charge (-1 + 1 = 0). So H₂CO₃ is the conjugate acid of HCO₃⁻. The H₂O becomes OH⁻. It has one less H atom and one more – charge. So OH⁻ is the conjugate base of H₂O. Ernest Z. · 25 · Jul 3 2014 elden ring early greatswords
