Which response includes all of the following

LiOH, KOH, Ni(OH)2, Mg(OH)2, Ca(OH)2
that are insoluble bases, and no others?

insoluble bases include, Ni(OH)2 and Mg(OH)2.

To identify the insoluble bases among LiOH, KOH, Ni(OH)2, Mg(OH)2, and Ca(OH)2, we need to refer to the solubility rules for hydroxides:

1. LiOH - Soluble (LiOH is generally soluble, as lithium salts are in most cases)
2. KOH - Soluble (Potassium hydroxide is also soluble)
3. Ni(OH)2 - Insoluble (Nickel hydroxide is generally insoluble, except for some complex compounds)
4. Mg(OH)2 - Insoluble (Magnesium hydroxide is insoluble)
5. Ca(OH)2 - Insoluble (Calcium hydroxide is also insoluble)

From the above information, the insoluble bases from the given options are Ni(OH)2, Mg(OH)2, and Ca(OH)2.

To determine which of the following compounds are insoluble bases, we need to refer to a solubility table. Solubility tables provide information on the solubility of various compounds in water.

First, let's identify the cations (positive ions) and anions (negative ions) present in each compound:

LiOH: Li+ (cation), OH- (anion)
KOH: K+ (cation), OH- (anion)
Ni(OH)2: Ni2+ (cation), OH- (anion)
Mg(OH)2: Mg2+ (cation), OH- (anion)
Ca(OH)2: Ca2+ (cation), OH- (anion)

Now, let's check the solubility of the hydroxides (OH-) in water using a solubility table. According to most solubility tables, hydroxides are generally insoluble, except for hydroxides of alkali metals (Group 1A) and some alkaline earth metals (Group 2A).

In this case, LiOH and KOH are soluble because they contain alkali metals (Li and K) that form soluble hydroxides.

In contrast, Ni(OH)2, Mg(OH)2, and Ca(OH)2 are insoluble bases because they are hydroxides of transition metals (Ni) and alkaline earth metals (Mg and Ca), which tend to form insoluble hydroxides.

So, the answer is: Ni(OH)2, Mg(OH)2, and Ca(OH)2 are the compounds among LiOH, KOH, Ni(OH)2, Mg(OH)2, Ca(OH)2 that are insoluble bases.

I don't understand the question.
