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

We have a 0.1M solution of NH_(2)CONH_(2),H_(3)PO_(3) and H_(3)PO_(4) then which of the following statement is correct, if we consider 100% dissociation for H_(3)PO_(3) and H_(3)PO_(4)

Assertion: H_(3)PO_(4) and H_(3)PO_(3) both are present in fertilizers. Reason: H_(3)PO_(3) increases the solubility of fertilizers.

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

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

1 mol of H_(3)PO_(2), H_(3)PO_(3) and H_(3)PO_(4) will neutralise x mol NaOH , y mol of Ca(OH)_(2) and z mol of Al(OH)_(3) respectively (assuming all as strong electrolytes). x, y, z are in the ratio of:

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.

For, H_(3)PO_(4)+H_(2)OhArrH_(3)O^(+)+H_(2)PO_(4)^(-), K_(a_(1)) H_(2)PO_(4)+H_(2)OhArrH_(3)O^(+)+HPO_(4)^(2-), K_(a_(2)) HPO_(4)^(2-)+H_(2)OhArrH_(3)O^(+)+PO_(4)^(3-), K_(a_(3)) The correct order of K_(a) values is:

Statement-1: HBr can be obtained by treating NaBr with H_(3)PO_(4) . Statement-2: H_(3)PO_(4) is stronger acid than HBr.

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