At 25°c, a saturated solution of cerium(iii) hydroxide (ce(oh)3) contains 5.1 × 10–6 moles of the compound in one liter of solution.

what is the set-up for determining ksp?

The solubility product of cerium(III) hydroxide in the given solution is .

Explanation:

Concentration of cesium hydroxide =

                    S       3S

1 mol of cerium(III) hydroxide gives 1 mol of cerium ion and 3 moles of hydroxide ions.

Concentration of cerium ion =

Concentration of hydroxide ion =

The solubility prodcut will be given as:

The solubility product of cerium(III) hydroxide in the given solution is .

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
