How do you find the Ksp of an extremely insoluble compound? Like for a soluble compound you would write the dissociation equation and use the molar solubility provided & the ratios in the balanced equation to calculate Ksp, but for an insoluble compound is it still accurate to write the dissociation equation and calculate it from there, if it's barely going to dissociate? I don't remember if we covered this in class, and I searched up the definiton of Ksp, and it said it calculates the solubility of a "sparingly soluble compound," is that true?

nvm I understood, you can find ksp of insoluble compounds using dissociation equation
