ammonium fluoride, NH4F
(i) Explain how the two anions (phosphate and sulfate) could be separated making use of the solutions above and an equipment like a Büchner funnel that can collect precipitated solids on a filter while allowing the remaining solution to pass through into a flask.
(Hint: Refer to the solubility table at the end of this document to determine what could be added to precipitate only one of the two anions.)
(ii) What is a balanced chemical reaction equation for any relevant precipitation reaction, including the states of all chemical species.
