WebK sp = [Zn 2+] 3 [AsO 43 ¯] 2. Note how the mercury (I) ion is written. Hg 22+ is correct. Do not write it as 2Hg +. Writing [Hg +] 2 in the K sp expression is wrong. Here are ten chemical formulas. Write the chemical equation showing how the substance dissociates and write the K sp expression. 1) AlPO 4. 2) BaSO 4. Web5 dec. 2024 · The K c expression is: If you compare this with the previous example, you will see that all that has happened is that the expression has turned upside-down. Its value at room temperature will be approximately 1/4 (0.25). It is really important to write down the equilibrium reaction whenever you talk about an equilibrium constant.
