Yes – she could ask for a solution of phosphate since it world contain only free
phosphate ions
b.
Yes – she could ask for a solid sample of phosphate ions
c.
Yes – as long as she is grounded to prevent shock from the ionic charge
d.
No – she should ask for a pure sample of dihydrogen phosphate ion
e.
No – phosphate ion can’t exist by itself (must have some cation with it –
therefore she should ask for sodium phosphate, potassium phosphate or something
like that.
