One mole of calcium phosphide on reaction with excess of water gives

A

one mole of phosphate

B

Two moles of phosphoric acid

C

Two moles of phosphine

D

One mole of phosphorus pentoxide

Text Solution

Verified by Experts

The correct Answer is:
C
`Ca_(3)P_(2) + 6H_(2)O to 2PH_(3) + 3Ca(OH)_(2)`
1 mol of `Ca_(3)P_(2)` gives 2 moles of `PH_(3)`.
