Question
Learning goal 2: Sodium hydroxide is mixed with magnesium sulfate.Using the solubility chart, determine whether a precipitate will form.NoYes, sodium sulfateYes, magnesium hydroxide
Solution
When sodium hydroxide (NaOH) is mixed with magnesium sulfate (MgSO4), a double displacement reaction occurs. The products of this reaction are sodium sulfate (Na2SO4) and magnesium hydroxide (Mg(OH)2).
To determine whether a precipitate will form, we need to refer to a solubility chart. A solubility chart provides information about the solubility of various compounds in water.
-
Looking at the solubility chart, we find that sodium sulfate (Na2SO4) is soluble in water. Therefore, it will not form a precipitate.
-
On the other hand, magnesium hydroxide (Mg(OH)2) is listed as insoluble in water. Therefore, it will form a precipitate.
So, the answer is "Yes, magnesium hydroxide".
