Ammonia Nh3 Is Very Soluble In Water Whereas Phosphine. See liquid ammonia as a solvent. Water also has hydrogen-bonding intermolecular attractive forces. Ammonia is a gas and it is soluble in water. Therefore N atom gets partial negative charge and H atoms get partial positive charge.
P has the hydrogens and the lone pair of electrons but it does not have a high electronegativity value so it does not H-bond to water as much. Water also has hydrogen-bonding intermolecular attractive forces. The Correct Answer is Both NH3 are pyramidal molecules which are attracted to water molecules by dipole dipole and dispersion forces. See liquid ammonia as a solvent. Solubility Solubility is the property of a solid liquid or gaseous chemical substance called solute to dissolve in a solid liquid or gaseous solvent. Both ammonia and phosphine PH 3 are soluble in water.
As phosphorous is less electronegative than nitrogenthus is not as polar as ammonia and is slightly soluble in polar.
Water also has hydrogen-bonding intermolecular attractive forces. Which is least soluble and why. What mass in grams of ammonia will react with 2800E3 kg of Phosphoric acid. Which is least soluble and why. It is too small to be hydrated by water molecules. The solubility of ammonia in water determines the polarity of ammonia.
