In a saturated solution of magnesium phosphate, [mg2+] = 2.4 * 10^-5 m and [po4^3-] = 1.6 * 10^-6. what is the solubility of magnesium phosphate?

When iron oxide powder and aluminum powder react, they undergo a single-displacement reaction to form iron and aluminum oxide. The reaction releases a great deal of light and enough thermal energy to melt the iron that forms.
