What is the chemical equation for the second ionization reaction of phosphoric acid with water?
The second ionization reaction of phosphoric acid (H3PO4) with water is: H2PO4- (aq) + H2O (l) ⇌ H3O+ (aq) + HPO4^2- (aq)
What is the unit of acid ionization constant?
The unit of acid ionization constant is dimensionless because it is a ratio of the concentration of products to reactants in a chemical equilibrium expression. It is denoted by a lowercase "k" (ka) for weak acids and is used to quantify the extent to which an acid dissociates in water.
Is phosphoric acid strong or weak acid?
Phosphoric acid is considered a weak acid. While it can donate multiple protons (H+ ions), its dissociation in water is not complete, resulting in a lower degree of ionization compared to strong acids like hydrochloric acid.
What indicates the ionization constant for an acid?
An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid-base reactions. The equilibrium can be written symbolically as: HA A− + H+,

Which acid in table 19.6 would you expect to have the lowest ionization constant?
To determine which acid has the lowest ionization constant (Ka), we look for the weakest acid among the options presented in table 19.6. Generally, weak acids have lower ionization constants than strong acids. Therefore, the acid with the least ability to donate protons (H⁺) in solution, often characterized by a higher pKa value, would be expected to have the lowest ionization constant.
Is poly phosphoric acid different from phosphoric acid?
I don't think so.poly phosphoric acid and phosphoric acid have same moleculer structure.http://harvestchem.iblogger.org
What is the acid name H3PO4?
phosphoric acid
The acid dissociation constant for an acid dissolved in water is equal to the?
The acid dissociation constant (Ka) for an acid dissolved in water is the equilibrium constant for the dissociation reaction of the acid into its ion components in water. It represents the extent of the acid's ionization in water.
What is the reaction of phosphoric acid with nitric acid?
phosphoric acid
What is the difference between ortho-phosphoric acid and phosphoric acid?
Ortho-phosphoric acid is a specific form of phosphoric acid, where the phosphorus atom is bonded to three hydroxyl groups. Phosphoric acid, on the other hand, is a more general term that can refer to any acid containing phosphorus, including ortho-phosphoric acid, as well as pyrophosphoric acid and metaphosphoric acid.
How can I make a 9N Phosphoric Acid solution?
To make a 9N (normal) Phosphoric Acid solution, you will need to know the concentration of your Phosphoric Acid. The formula to calculate the volume of Phosphoric Acid required is: Volume (in liters) = (Desired Normality * Equivalent Weight of Phosphoric Acid * Volume of Solution) / Concentration of Phosphoric Acid.
African country that is the worlds largest exporter of phosphates fertilizers valued for their phosphoric acid?
