12 Ιουλ 2023 · Weak bases react with water to produce the hydroxide ion, as shown in the following general equation, where B is the parent base and BH+ is its conjugate acid: \[\ce{B(aq) + H2O(l) <=> BH^{+}(aq) + OH^{−} (aq)} \label{16.5.4}\]
15 Απρ 2024 · Calculate the pH of a solution of a weak monoprotic weak acid or base, employing the "five-percent rule" to determine if the approximation 2-4 is justified. Predict whether an aqueous solution of a salt will be acidic or alkaline, and explain why by writing an appropriate equation.
27 Σεπ 2022 · NH 4 Cl is an example of an acid salt. The molecule NH 3 is a weak base, and it will form when it can, just like a weak acid will form when it can. So there are two general rules: If an ion derives from a strong acid or base, it will not affect the acidity of the solution.
Salts containing the anion H 2 PO 4-1 are weakly acidic. The tendency of this ion to dissociate is greater than its tendency to hydrolyze, that is, its K a 2 is larger than its K b. Because H 2 PO 4-1 is weakly acidic and of low toxicity, it is used as the acid in some baking powders.
Phosphoric acid’s formula is written as H 3 PO 4. This acid is a non-toxic acid and in its pure form, it is a solid at room temperature. It has a molar mass of 97.99 g/mol. H 3 PO 4 is one of the most important and useful mineral acids.
Each successive dissociation step occurs with decreasing ease. Thus, the ion H2PO4 ̅ is a very weak acid, and HPO4 2 ̅ is an extremely weak acid. Salts of phosphoric acid can be formed by replacing one, two or three of the hydrogen ions.
