Pick a salt, then follow the whole chain from Ksp to molar solubility. The ion ratio sets the formula, so a 1:1 salt, a 1:2 salt and a 3:2 salt each need a different root. Slide the constant and watch the beaker answer.
Slide the exponent to see how a smaller constant shrinks the solubility. The shrink is gentler for salts that release three or five ions.
