Ionisable `H` atoms in `H_(3)PO_(3)` is X and in `H_(3)PO_(2)` is y .Then ratio of x,y is

Ionistable H atom in H_(3)PO_(3) is x and in H_(3)PO_(2) is y. Then ratio of x:y is

H_(3)PO_(3) is ..... acid

For H_(3)PO_(3) and H_(3)PO_(4) the correct choice is

What happens when H_(3) PO_(3) is heated ?

The oxo-acids of P_(2)O_(5) is H_(3)PO_(4)

H_(3)PO_(3) is diprotic (or dibasic). Why ?

H_(3)PO_(2),H_(3)PO_(3) and H_(3)PO_(4) which of them are tribasic acids

In H_(3)PO_(4) which of the following is true?

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.

The addition of NaH_(2)PO_(4) to 0.1M H_(3)PO_(4) will cuase
