WebJan 30, 2024 · To find K a1 of Hydrosulfuric acid (H 2 S), you must first write the reaction: H 2 S ⇌ H + + H S − Dividing the products by the reactants, we then have: K a 1 = [ H +] [ H S −] [ H S −] To find K a2, we start with … WebTriprotic Acids. Our techniques for working diprotic acid or diprotic base equilibrium problems can be applied to triprotic acids and bases as well. To illustrate this, let's calculate the H 3 O + , H 3 PO 4, H 2 PO 4-, HPO 42- … WebTherefore, the numerical value of Ka is a reflection of the strength of the acid. Weak acids with relatively higher Ka values are stronger than acids with relatively lower Ka values. Because strong acids are essentially 100% ionized, the concentration of the acid in the denominator is nearly zero and the Ka value approaches infinity. pottery books uk
