Answer:
1) high pH is required
2) other ions are precipitated along with the strontium ions
Explanation:
According to the solubility rules all phosphates are insoluble except those of sodium, potassium, and ammonium. This implies that strontium phosphate is insoluble in water. This explains why strontium ions can be precipitated from drinking water supply using phosphate. The main problem with the precipitation of strontium using phosphate is that it usually requires a high pH as the precipitation occurs under very alkaline conditions.
The main reason why the results may not be accurate is that other ions are precipitated along with the strontium such as calcium ions and magnesium ions. This may lead to inaccurate determination of the amount of strontium ions present.
Answer:
Explanation:
The fundamental issue for precipitation of Strontium Phosphate, is that the other metal cations (Calcium, Barium, Iron, and so on.), present in the town water, are likewise encouraged as Phosphate. In this manner, alongside Strontium Phosphate, Phosphates of a few different cations are additionally encouraged. In this way, Strontium Phosphate can't be weighed precisely. This will prompt off base outcomes.
The response will be Exothermic, if the temperature of response increments.
