Web69 rows · Table of Solubility Product Constants (K sp at 25 o C). Type Formula K sp; … WebKsp means solubility product. When Ksp value is low, it indicates that compound has a lower solubility in water. Lets take several metal sulfides to learn this. Ksp of CuS : 1 * 10 -36 mol 2 dm -6. Ksp of ZnS : 1 * 10 -23 mol 2 dm -6. You see these metal sulfide's Ksp values are very low and they form precipitates in the water.
