What is meant by number of replaceable ions?
The number of replaceable ions refers to the total number of ions in a compound that can be exchanged or replaced with other ions through a chemical reaction or process, such as ion exchange or precipitation. This value is important in understanding the reactivity and behavior of the compound in different environments.
Why is KH2PO4 monobasic and K2HPO4 dibasic?
KH2PO4 is monobasic because it contains one replaceable hydrogen ion for each molecule of the compound. K2HPO4 is dibasic because it contains two replaceable hydrogen ions for each molecule of the compound. The number of replaceable hydrogen ions determines whether a compound is classified as monobasic, dibasic, tribasic, etc.
How do you find replaceable hydrogen ions in an acid?
In any Arrhenius' acid if you want to find the no: of replaceable hydrogen 1.draw the structure of that compound (its really tricky!!!) 2.now locate the hydrogen which are not directly attached to the central atom. 3.that will be the no: of replaceable h ions.see to it that there is not a dibond or co ordinate bond.
Why is H3PO4 an acid?
H3PO4 is an acid because it can donate a hydrogen ion (proton) when dissolved in water, resulting in the formation of hydronium ions. This gives the solution acidic properties, as it increases the concentration of H+ ions. Additionally, phosphoric acid (H3PO4) has a dissociation constant (Ka) which indicates its ability to donate hydrogen ions in solution.
How does H3PO4 dissociate?
Phosphoric acid (H3PO4) dissociates in water to release three hydrogen ions (H+) and one phosphate ion (H2PO4-). This dissociation process occurs in stages, with each hydrogen ion being released successively.

What is the number of replaceable hydroxyl ions in a base?
In a base, the number of replaceable hydroxyl ions (OH⁻) typically corresponds to the base's valency or the number of hydroxide ions it can donate in a reaction. For example, in a strong base like sodium hydroxide (NaOH), there is one replaceable hydroxyl ion per formula unit. In contrast, for a base like barium hydroxide (Ba(OH)₂), there are two replaceable hydroxyl ions. Thus, the number varies depending on the specific base.
What are the relative acidities of H3PO4 and H2PO4 -ion?
H3PO4 > H2PO4-PH 0.1 M SolutionsH3PO4 PH=1.5H2PO4- PH=4.4HPO42- PH=9.3PO43- PH=12
Why H3PO3 is a dibasic acid?
H3PO3 is a dibasic acid because it has two replaceable hydrogen ions that can be ionized in a solution to form hydrogen ions (H+) and a phosphate ion (H2PO3-). This allows it to donate two protons and form two acidic solutions.
What is acidity of bases?
The number of replaceable hydroxyl (OH-) Ions in a base is called the acidity of that base.
When an acid ionizes in water what happens to the number of hydrogen ions?
the number of hydrogen ions (charges) given by the acid will be the same as the anions
Why is water considered to be a neutral?
Because the number of hydrogen ions are the same as the number of Hydroxide ions.
What is basicity of an acid?
Basicity of an acid refers to the number of hydrogen ions (H+) that can be donated by the acid in a chemical reaction. It is a measure of the strength of an acid in donating protons. Acids with higher basicity can donate more protons and are considered stronger acids.
