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.
Wet process. In the wet process, a phosphate-containing mineral such as calcium hydroxyapatite and fluorapatite are treated with sulfuric acid. [21] Ca5(PO4)3OH + 5 H2SO4 → 3 H3PO4 + 5 CaSO 4 + H2O. Ca5(PO4)3F + 5 H2SO4 → 3 H3PO4 + 5 CaSO 4 + HF. Calcium sulfate (gypsum, CaSO4) is a by-product, which is removed as phosphogypsum.
16 Σεπ 2022 · Define a strong and a weak acid and base. Recognize an acid or a base as strong or weak. Determine if a salt produces an acidic or a basic solution.

Phosphoric Acid is a weak acid with the chemical formula H 3 PO 4. Phosphoric Acid is an acid-containing four atoms of oxygen, one atom of phosphorus, and three atoms of hydrogen. It is also known as phosphoric (V) acid or orthophosphoric acid. It is present in teeth and bones and helps in metabolic processes.
27 Σεπ 2022 · Strong acids and bases are 100% ionized in aqueous solution. Weak acids and bases are less than 100% ionized in aqueous solution. Salts of weak acids or bases can affect the acidity or basicity of their aqueous solutions.
We can determine whether a salt solution will be acidic, basic, or neutral by considering the reactivity of both the cation and the anion with water. If neither species reacts with water, the solution will be neutral.
