No, PH5 is not a polar molecule. The molecule is symmetrical with the same atoms (hydrogen and phosphorus) attached to the central phosphorus atom, resulting in no net dipole moment.
Yes, PH5 has bond polarity because phosphorus and hydrogen have different electronegativities, resulting in a partial positive charge on hydrogen and a partial negative charge on phosphorus within the molecule.
If you dilute a pH 5 solution with water, the pH of the resulting solution will increase and become closer to neutral (pH 7). The more water you add, the closer the pH of the solution will approach 7.
The bond angle in PH5 would likely be close to 90 degrees since phosphorus can accommodate five bonding pairs around it in a trigonal bipyramidal geometry. However, due to the repulsion between the bonding pairs, the actual bond angle may deviate slightly from the ideal angle of 90 degrees.
Phosphorus pentahydride, PH5, cannot exist because phosphorus typically forms stable compounds with a maximum coordination number of five due to its electron configuration. In PH5, the phosphorus atom would need to have a coordination number of six, which is energetically unfavorable. Furthermore, there are no known stable compounds of phosphorus in the +5 oxidation state with hydrogen.
