1 mole of each of Ca(OH)(2) and H(3) PO(...

1 mole of each of `Ca(OH)_(2)` and `H_(3) PO_(4)` are allowed to react under dilute conditions . The maximum number of moles of `Ca_(3) (PO_(4))_(2)` formed is

A

1

B

`1//2`

C

`1//3`

D

3

Text Solution

Verified by Experts

The correct Answer is:
C
`3Ca(OH)_(2)+2H_(3)PO_(4)rarrCa_(3)(PO_(4))_(2)+6H_(2)O`
`3Ca(OH)_(2)rarr2H_(3)PO_(4)`
`therefore Ca(OH)_(2)` is limiting reagent.
`3Ca(OH)_(2)rarr1 Ca_(3)(PO_(4))_(2)`
`1 rarr?=1//3`
