The multiplication of ions of a specific compound when particularly dissolved in an aqueous solution becomes equivalent to solubility product. Additionally, a solution is miscible when it can be mixed together at any ratio- this mainly applies to liquids, like ethanol, C2H5OH, and water, H2O. The solubility product expression is as follows: Ksp = [Ba2 +][SO2 4] = 1.08 10 10 B To solve this problem, we must first calculate the ion product: Q = [Ba2 +][SO2 4] using the concentrations of the ions that are present after the solutions are mixed and before any reaction occurs. One of its applications is the detection of 511 keV gamma photons in positron emission tomography.
