Question

What would happen if you mixed aqueous magnesium bromide with aqueous sodium phosphate?

Answer 1

Mixing aqueous magnesium bromide with sodium phosphate results in a double displacement reaction forming magnesium phosphate and sodium bromide.

Step-by-step explanation:

When you mix aqueous magnesium bromide with aqueous sodium phosphate, a double displacement reaction, also known as a metathesis reaction, will occur. The cations (Mg2+ and Na+) will swap partners with the anions (Br− and PO43−), potentially forming new compounds.

The likely product in this case will be magnesium phosphate, which is slightly soluble in water and may precipitate depending on the solution's concentration, along with highly soluble sodium bromide remaining in the solution. The overall chemical equation for this reaction is:

MgBr2(aq) + Na3PO4(aq) → Mg3(PO4)2(s) + 6NaBr(aq)

Answer 2

When heated, solid calcium chlorate decomposes into calcium chloride solid, releasing oxygen gas. (c) Solutions of barium bromide and sodium phosphate combine to ... iodide are mixed together, forming solid silver iodide and aqueous .
