Answer the questions in the table below about the shape of the phosphorus hexachloride (pci^1_6) anion. what word or two-word phrase best describes the shape of the pci^1_6 anion? what is the angle between the phosphorus-chlorine bonds? (if there is more than one angle, pick the smallest.)

Shape of PCl₆⁻¹, is octahedral.

Hybrdisation of PCl₆⁻¹ is sp³d².

This can be seen the image attached.

The angle between phosphorous and chlorine is 90⁰C. As it has octahedral geometry.

So the answer is as follows:

Shape of PCl₆⁻¹, is octahedral.

Hybrdisation of PCl₆⁻¹ is sp³d².

The angle between phosphorous and chlorine is 90⁰C.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
