First because the later ones are trying to take more H plus ions from an already negative ion, which is harder.

The largest ionization constant for phosphoric acid is typically considered to be Ka1, which corresponds to the first ionization step where one hydrogen ion is released from phosphoric acid. Ka1 for phosphoric acid is approximately 7.5 x 10^-3.

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?

The ionization constant for an acid is indicated by its acid dissociation constant, Ka. This constant represents the degree to which the acid dissociates into its ions in a solution. A higher Ka value indicates a stronger acid, while a lower Ka value indicates a weaker 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 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 many ionoization constant are associated with oxalic acid?

Oxalic acid (H2C2O4) has two ionization constants since it can donate two protons. The ionization constants represent the extent to which the acid dissociates in water to form ions.


What does the ionization constant tells us abuot the strength of an acid?

The ionization constant, also known as the acid dissociation constant (Ka), provides information about the extent to which an acid dissociates in water to form ions. A larger Ka value indicates that the acid is stronger because it dissociates more readily. Conversely, a smaller Ka value indicates a weaker acid that dissociates to a lesser extent.


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.
