Table of Acids with Ka and pKa Values* CLAS * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed. The pKa values for organic acids can be found in Appendix II of Bruice 5th Ed.

Use this acids and bases chart to find the relative strength of the most common acids and bases. This acid-base chart includes the Ka value for reference along with the chemical's formula and the acid’s conjugate base. The acid and base chart is a reference table designed to make determining the strength of acids and bases simpler.

1. Strong acids are listed at the top left hand corner of the table and have Ka values >1 2. Acid with values less than one are considered weak. 3. The strong bases are listed at the bottom right of the table and get weaker as we move to the top of the table.

2020年8月14日 · There is a simple relationship between the magnitude of Ka for an acid and Kb for its conjugate base. Consider, for example, the ionization of hydrocyanic acid (HCN) in water to produce an acidic solution, and the reaction of CN − with water to produce a basic solution: HCN (aq) ⇌ H + (aq) + CN − (aq) CN − (aq) + H2O (l) ⇌ OH − (aq) + HCN (aq)

TABLE OF CONJUGATE ACID-BASE PAIRS Acid Base K a (25 oC) HClO 4 ClO 4 – H 2 SO 4 HSO 4 – HCl Cl– HNO 3 NO 3 – H 3 O + H 2 O H 2 CrO 4 HCrO 4 – 1.8 x 10–1 H 2 C 2 O 4 (oxalic acid) HC 2 O 4 – 5.90 x 10–2 [H 2 SO 3] = SO 2 (aq) + H2 O HSO

Ka表示弱酸的电离常数，Ka越大，酸性越强， pKa 表示其负 对数。 在室温下（25°C），酸的电离常数称之Ka，Ka越大，酸性越强。 一般地，对于不低于二元的 弱酸，Kan＞Ka (n+1)（n∈N*） Ka是弱酸的电离常数，条件是在室温下（25°C）。 Ka表示弱酸的电离常数，Ka越大，酸性越强，pKa表示其负对数。

2013年10月12日 · 硫酸氢根的解离常数ka是多少hso4 - = h+ + so4 2-ka = 1*10^-2

电离常数（Ka）是指酸解离平衡反应中酸解离产生的氢离子（H+）和酸分子之间的相对浓度比值。 对于硫酸氢根的电离平衡反应（HSO4- + H2O ↔ H3O+ + SO42-），其电离常数可表示为：

（本来是打空格让数据在物质后面对齐，结果空格全被吞了。 （常见）酸按第一级电离常数大小排序： H2SO4 Ka1=1.0×10^3 Ka2=1.02×10-2 H2SO3 Ka1=1.23×10-2 Ka2=1.02×10-7 H3PO2 Ka=5.9×10-2 H2C2O4 Ka1=5.9×10-2 Ka2=6.4×10-5 H3PO3 Ka1=5.0×10-2 Ka2=2.5×10-7 H3…
