Phosphine

Many hundred ...

Question

Many hundred years ago, a ship was transporting calcium carbide and calcium phosphide (stored in different container). By chance sea-water entered sea and luminous flame appeared a ghost would have come. However, a chemist travelling in it explained it based on reactions. These reactions are
$C a C_{2} C a l c i u m C a r b i d e + 6 H_{2} O ⟶ C a (O H)_{2} + C_{2} H_{2} A c e t y l e n e C a_{3} P_{2} C a l c i u m p h o s p h i d e + 6 H_{2} O ⟶ 3 C a (O H)_{2} + 2 P H_{3} P h o s p h i n e$

Solution

The correct option is A True
$C a C_{2}$ and $C a_{3} P_{2}$ both were stored in containers but when water reacted with them $P H_{3}$ and $C_{2} H_{2}$ were formed. Some highly spontaneously flammable gases ( $P_{2} H_{4}$ and $H_{2}$ ) are also formed and as a result of this, $C_{2} H_{2}$ gas also burns (which people assumed as a ghost). So the reaction and statements are true.
