WebMar 29, 2024 · Plug the values into the formula. The equation for the Ksp of Ca (OH)2 is the concentration [Ca2+] times the concentration [OH-] taken to the second power, since the OH- has a coefficient of 2 in the balanced equation. Plug the concentrations of each of the products into the equation to calculate the value of Ksp. ADVERTISEMENT. WebMay 13, 2024 · So, you can't calculate the EW of C a O without any reaction reference. Still, usually C a O reacts through 2 electron exchange mechanism, in other words, C a O, on dissociation, gives total cationic charge +2 and total anionic charge -2. C a O = C a X 2 + + O X 2 −. Hence, in this case of calculating EW, you have to consider n = 2 and so the ...
