What should be the order of acidic strength in the series `H_(3)PO_(4)`, `H_(3)PO_(3)`, and `H_(3)PO_(2)`?

Assertion: There is a very little difference in acidic strengths of H_(3)PO_(4),H_(3)PO_(3) and H_(3)PO_(2) . reason: Number of unprotonated oxygen (=O) responsible for increase of acidic strength due to inductive effective remains the same.

The true statement for the acids of phosphorus, H_(3)PO_(2), H_(3)PO_(3) and H_(3)PO_(4) is

The true statement of the acids of phosphorus H_(3)PO_(2),H_(3)PO_(3) and H__(3)PO_(4) is :

Assertion (A): There is very little difference in acid strength of H_(3)PO_(4), H_(3)PO_(3) ,and H_(3)PO_(2) . Reason (R) : The hydrogens in these acids are not all bonded to oxygens. The electrone-grativities of P and H are almost the same.

What is the basicity of H_(3)PO_(4) ?

Find the total number of diprotic acids among the following: H_(3)PO_(4), H_(2)SO_(4), H_(3)PO_(3)

The total number of diprotic acids among the following is H_(3)PO_(4), H_(2)SO_(4), H_(3)PO_(3) H_(2)CO_(3), H_(2)S_(2)O_(7), H_(3)BO_(3) H_(3)PO_(2), H_(2)CrO_(4), H_(2)SO_(3)

Arrange the following in increasing order of the property indicated : (a) H_(3)PO_(3), H_(3)PO_(4), H_(3PO_(2) ("Reducing Character") (b) NH_(3), PH_(3), AsH_(3), SbH_(3), BiH_(3) ("Basic Strength")

State true or false : The geometry of phosphorus in H_(3)PO_(2),H_(3)PO_(3) and H_(3)PO_(4) is tetrahedral

The false statement of the acids of phosphorus H_3 PO_2, H_3 PO_3 and H_3 PO_4 is
