To test for the presence of phosphate (PO4 3-) in water, you can use the molybdenum blue method. This method involves adding ammonium molybdate followed by ascorbic acid and sulfuric acid to the sample, which forms a blue complex in the presence of phosphate ions. The intensity of the blue color is proportional to the phosphate concentration in the water sample.

Potassium phosphate and barium acetate equation?

The reaction between potassium phosphate (K3PO4) and barium acetate (Ba(C2H3O2)2) will produce barium phosphate (Ba3(PO4)2) and potassium acetate (KCH3COO). The balanced chemical equation for this reaction is 3K3PO4 + Ba(C2H3O2)2 -> Ba3(PO4)2 + 6KCH3COO.


What is the chemical equation of magnesium and phosphorus acid?

3Mg(s) + 2H3PO4(aq) ---> 3H2(g) + Mg3(PO4)2(s)I believe the equation is: Mg + H3PO4 ---> H2 + Mg3PO4. It should be Mg3(PO4)2 because magnesium has a charge of +2 (Mg+2), and phosphate has a charge of -3 (PO4-3), which would become Mg3(PO4)2. Balanced, the equation is 3Mg + 2H3PO4 ---> 3H2 + Mg3(PO4)2

What is the net ionic equation for sodium phosphate and magnesium nitrate?

The net ionic equation for this reaction is:3Mg2+(aq) + 2PO43-(aq) -->Mg3(PO4)2(s)How to get this answer:To write the net ionic equation, you can start with the molecular equation:2Na3PO4(aq) + 3Mg(NO3)2(aq) --> 6NaNO3(aq) + Mg3(PO4)2(s)The molecular equation can be used to write the full ionic equation. To do this, you break down everything that is aqueous into its ionic constituents:2Na+(aq) + 2PO43-(aq) + 3Mg2+(aq) + 6NO3-(aq) --> 6Na+(aq) + 6NO3-(aq) + Mg3(PO4)2(s)You can then cross out whatever is the same on both side to get your net ionic equation:3Mg2+(aq) + 2PO43-(aq) -->Mg3(PO4)2(s)
