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.
Phosphoric acid (H3PO4) can donate 3 replaceable hydrogen ions. This is because each hydrogen atom in the formula can dissociate and release a positive hydrogen ion in solution.
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.
In a nitric acid solution, you would find nitrate ions (NO3-) and hydrogen ions (H+). Nitric acid (HNO3) ionizes in water to form nitrate ions and hydrogen ions.
Hydrogen chloride (HCl) contain, of course, hydrogen and chlorine in the molecule.
The equivalent mass of sulfuric acid (H2SO4) is calculated as its molar mass divided by the number of replaceable hydrogen ions it can donate. Since sulfuric acid can donate 2 hydrogen ions (H+), the equivalent mass is half of the molar mass. Therefore, the equivalent mass of sulfuric acid is approximately 49 g/mol.

No. Na2HPO4 is only a monobasic acid, corresponding to the remaining hydrogen atom. This is a very weak acid.

Since sulfuric acid can donate 2 hydrogen ions (H+), the equivalent mass is half of the molar mass. Therefore, the equivalent mass of sulfuric acid is approximately 49 g/mol.
Citric acid is considered tribasic because it has three carboxylic acid groups that can donate hydrogen ions in a solution, making it capable of forming three different types of salts. This property is what classifies citric acid as tribasic.
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.
Concentrated hydrochloric acid is stronger and more acidic than concentrated acetic acid because it fully dissociates into hydrogen ions and chloride ions in solution, while acetic acid only partially dissociates into hydrogen ions and acetate ions. Therefore, hydrochloric acid would have more hydrogen ions in solution.
An acid contains more hydrogen ions than hydroxide ions. Acids release hydrogen ions (H+) in water, while bases release hydroxide ions (OH-).
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.
A strong acid is an acid that fully dissociates into its ions in water, releasing a high concentration of hydrogen ions (H+) into the solution. Hydrochloric acid (HCl) is an example of a strong acid as it dissociates completely into hydrogen ions and chloride ions when dissolved in water.
