1) NaOH : two top alkaline earth metals' solubility is decreasing as we can see from cloudy to lots of solid and two bottom metals' solubility is also decreasing in observing difference amount of solid between Sr(NO3)2 and Ba(NO3)2
2) NaCl: all of the alkaline earth metals are soluble.
3) NABr: all of the alkaline earth metals are soluble.
4) NaI: all of the alkaline earth metals are soluble.
5) Na2SO4: solubility of alkaline earth metals is decreasing from clear to solid and cloudy.
6) Na2CO3: solubility of alkaline earth metals from Mg(No3)2 to Sr(NO3)2 is decreasing and after Sr(NO3)2, solubility is increasing.
7) Na2C2O4: solubility of alkaline earth metals is decreasing from clear to solid and cloudy.

Compare the solubilities of the lead compounds with those of the alkaline earth metals How are the solubilities similar and different?
Look at the position of Pb in the periodic table and the postion of the Alkali Earth metals. Alkali Earth Metals are in noble-gas configuration when they are doubly charged cations. Lead however is on the right hand side, and would like to have more electrons to get into that stablest configuration; making the bonds in lead-compounds more covalent -and stronger- in nature. Insoluble compounds have lattice enthalpies higher than the enthalpy of solvation. Now since Alkali Earth metals like to be in ionic states; their compounds will dissolve in general more easily than the same compounds with lead, since usually the lattice energy of lead compounds is much higher (In case of insoluble compounds higher than the energy that would be released upon solvation, which thus doesn't occur).
Compare and contrast the reaction of alkaline earth metals with their salts?
All alkaline earth metals and their salts are reactive and they have a blue-print that identifies them as an alkaline earth metal but metals exist as metals, and salts as salts, with different structural compounds.
Why are neither the alkali metals nor the alkaline earth metals found in nature?
Because these metals are very reactive and readily form compounds.
Why are neither the alkali metals nor the alkaline-earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
Why is Potassium an Alkaline Earth Metal?
Potassium is not an alkaline earth metal, it is an alkali metal. The metals in the leftmost column of the periodic table. They are noted for their high reactivity and for the fact that most of their compounds are basic.

Is an metal acidic or alkaline?
Pure metals are neither, no pure element is and acid or an alkali, it is only compounds made from elements that have this property. When metals form compounds those compounds are typically alkaline.
Why are alkaline metals mostly compounds?
Alkaline metals are usually found only as compounds in Nature because these metals are very active chemically and will combine with many commonly found substances such as water.
Why is group 1 metals called alkali metals?
They're metals that form alkaline compounds when they react with water.
Is a metal an acid or alkali?
its definitley not acid Some metals are called alkali metals or alkaline earth metals because they often form alkaline compounds; but metals are not alkali or acids.
in general compounds formed from active metals and hydroxide ions are?
Alkaline.
How are alkali metals different from alkaline metals?
The alkali metals are generally more reactive than the alkaline earth metals. They form 1+ ions while the alkaline earth metals form 2+ ions. Alkali metal compounds tend to be more soluble in water than alkaline earth metals.
Compare and contrast the reaction of alkaline earth metals with their salts?
All alkaline earth metals and their salts are reactive and they have a blue-print that identifies them as an alkaline earth metal but metals exist as metals, and salts as salts, with different structural compounds.
Why are neither the metals nor the alkaline-earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
Why are neither the alkali metals nor the alkaline earth metals found in nature?
Because these metals are very reactive and readily form compounds.
What forms ionic compounds?
Alkali metals , alkaline earth metals and halogens are most important ionic compound former .
Why are neither the alkali metals nor the alkaline-earth metals found uncombined in nature?
Because these metals are very reactive and readily form compounds.
