nickel ion forms the complex ion hexaamminenickel (II) with a formation constant of(Kf) of 5.6 x 10 ^8. initially the complex is formed when .002 M nickel sulfate is added to .10 M ammonia. predict whether nickel (II) hydroxide will precipitate from the solution when .01 M sodium hydroxide is added to the complex ion. the Ksp for Ni(OH)2 is 2.0 x 10^ -15
Combine the above two equations with that for the formation of liquid water and use addition and/or subtraction(i.e. Hess's Law) to arrive at the equation for the formation of magnesium oxide.
