Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. It is a major industrial ...
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.
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.
1 ημέρα πριν · A weak base always forms a strong conjugate acid. In the case of H3PO4, it forms H2PO4- (dihydrogen phosphate anion) as its conjugate base after removing an acidic proton. Moreover, H3PO4 is a weak acid so according to the conjugate acid-base pair, its corresponding pair, H2PO4− is a strong conjugate base.
7 Μαΐ 2024 · What is the reason for the phosphoric acid HX3POX4 H X 3 P O X 4 being a weak acid despite having a structure similar to that of sulfuric acid HX2SOX4? H X 2 S O X 4? I found some sources claiming that the resonance of one oxygen with double-bonded oxygen blocks the resonance of that of OHX−, O H X −, destabilising the negative charge.
Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a mineral (inorganic) acid with the chemical formula H 3 P O 4. It is a crystalline solid at room temperature and pressure.
27 Σεπ 2022 · Learning Objectives. 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. Except for their names and formulas, so far we have treated all acids as equals, especially in a chemical reaction.
