`H_(3)PO_(4)` is a tribasic acid and one of its salts of `NaH_(2)PO_(4)`. What volume of 1 M NaOH should be added to 12 g `NaH_(2)PO_(4)` (molecular mass = 120 g/mole) to exactly convert it into `Na_(3)PO_(4)`

100 ml

200 ml

80 ml

300 ml

Text Solution

Verified by Experts

The correct Answer is:

`"Equivalents of NaOH"="equivalents of "NaH_(2)PO_(4)`
`1xx"v in Lit"=(12)/(60)`
`"v in Lit "=0.2=200ml`

The volume of KOH required from completing the titration is: a. 70 mL b. 35 mL c. 32 mL d. 16 mL

The chemical name of NaH_(2)PO_(4) is -

H_(3)PO_(4) is tribasic while H_(3)PO_(3) is dibasic. Explain.

STATEMENT -1 : H_(3)PO_(4) is a tribasic acid. and STATEMENT -2 : In H_(3)PO_(4) , only two H-atoms are replaceable.

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

Statement-1 : Both H_(3)PO_(3) and H_(3)PO_(4) have the same number of hydrogen atoms but H_(3)PO_(4) is a tribasic acid and H_(3)PO_(3) is a dibasic acid. Statement-2 : 1 mol of H_(3)PO_(3) is neutralised by 2 mol of NaOH while 1 mol of H_(3)PO_(4) is neutralised by 3 mol of NaOH
