- (For Exercises 4546) Solutions containing nickel(II) ion are usually bright green in color. When potassium hydroxide is added to such a nickel(II) solution, a pale-green fluffy solid forms and settles out of the solution. The fact that a reaction takes place when potassium hydroxide is added to a solution of nickel(II) ions is an example of a properly. . The fact that a solution of nickel(II) ion is bright green is an example of a property.arrow_forwardIn Chapter 3, we learned that all matter is composed of atoms. In this chapter, we learned that most common substances are either compounds or mixtures of compounds. How can these both be true?
