Phosphoric acid, also known as orthophosphoric acid or phosphoric (V) acid, is a weak acid with the chemical formula H ₃PO ₄. The pure compound is a colorless solid. All three hydrogens are acidic to varying degrees and can be lost from the molecule as H+ ions.

Which is orthophosphoric acid?

Phosphoric acid It is a weak acid with the chemical formula H3PO4. Phosphoric acid is an acid containing four oxygen atoms, one phosphorus atom and three hydrogen atoms. It is also known as phosphoric (V) acid or orthophosphoric acid. It is found in teeth and bones and helps with metabolic processes.

What is the N factor of orthophosphoric acid?

Orthophosphoric acid is a tribasic acid; it has three replaceable hydrogen ions per mole. For acids, the n-factor is the alkalinity, which is defined by the number of hydrogen ions substituted.The n-factor of orthophosphoric acid is 3.

How do you calculate the n factor?

To calculate the n-factor of this salt, we Take one mole of reactant and find the number of moles of the element whose oxidation state changes. This is multiplied by the oxidation states of the elements in the reactants to give the total oxidation state of the elements in the reactants.

What is the N-factor of H 3 PO 4 ?

The H+ ions produced per molecule of acid dissociation are 3. Hence the n-factor of phosphate H3PO4 is 3.

What are the N-factors of H 3 PO 3 and 3 Po 3 ?

Phosphoric acid has an alkalinity of 2. This is because H3PO3 can provide two OH – ions, or it contains 2 replaceable H + ions.Therefore, the normality for a given phosphoric acid is 0.6 cattle.

Is H2PO4 a base or an acid?

Salts containing the anion H2PO4‾ are weak acid. The tendency of this ion to dissociate is greater than that of its hydrolysis, ie its Ka2 is greater than its Kb. Because H2PO4‾ is weakly acidic and has low toxicity, it is used as an acid in some baking powders.
