`PH_(3)` , forms bubbles when passed slowly in water but `NH_(3)` , dissolves. Explain why?

Explanation

Dissolution of `NH_(3)`, and `PH_(3)`, in water can be explained on the basis of H-bonding. `NH_(3)`, forms H-bond with water as N has an electronegativity higher than H so, it is soluble but `PH_(3)`, does not form H-bond with water as it has lower electronegativity so, it remains as gas and forms bubbles in water.
