Are Alkali metal hydroxides and alkaline earth metal hydroxides strong metals?

- Alkali metals are metals in Group I (far left column) such as Lithium, Sodium, Potassium, etc. They have a valence of -1.
- Alkali Earth Metals are in Group II (second column from the left) such as Berylium, Magnesium, Calcium, etc. and have a valence of -2.
One Hydroxide (OH-) ion will form an ionic bond with group 1 elements {Like NaOH }, and two Hydroxide ions will form an ionic bond with group 2 elements {like Ca(OH)2 }

Why Alkaline earth metals are harder than alkali metals?
It is because alkali metals are larger in size than alkaline earth metals.Also, the effective nuclear charge is more in case of alkaline earth metals. This makes their ionization enthalpies larger than alkali metals.
What are the properties of the alkaline earth metals?
They are shiny, silver, less malleable than alkali metals and they burn with bright flames. They also make strong bases (Opposite of acid).
Application of crown ethers in extraction of alkali and alkaline earth metals?
due to its behaviours of complexes crown ethers they act as strong phase transfer catalyst.
What is the importance of alkaline earth metals in human body?
Alkaline earth metals in the body play a huge role in health. For instance, calcium is the fifth most abundant in the human body. You need calcium for strong bones.
What is alkali dust?
maybe a dust that is really strong.
Alkali metal hydroxides and alkaline earth metal hydroxides are .?
strong bases
Alkali metal hydroxides and alkaline earth metal hydroxides are?
strong bases
What are alkails in?
Alkali metals: Li, Na, K, Rb, Cs, Fr. Alkali compounds: hydroxides.
What does sodium hydroxide and potassium hydroxide have in common?
Both of these compounds are strong alkali. Both of these are hydroxides of alkali metals. Both of these compounds dissolve in water vigorously.
Why are the alkali metals so named?
When alkali metals react with water they produce an alkali (basic) solution. No because they form basic oxides and they neutralise acids
Why are group 1 metals called alkaine metals?
They are actually called the alkali metals. They are called the alkali metals because many of the compounds they form are bases (alkaline) and in pure form they will react with water to produce strong bases.
KOH and LiOH are examples of?
Strong bases. They are alkali metal hydroxides.
Is aluminum hydroxide basic?
Only free, dissolved hydroxides of alkali and earth alkali metals are strong because (OH-)aq is a strong base only if it is a free ion in water.Iron is a (polyvalent) transition metal of which the hydroxides are (partially) non-dissolvable and can form mixed hydrate complex ions (e.g. Fe(OH)3(H2O) ).It is both a weak base and a weak acid!! (all reactions are equilibrium reactions of protolysis)basic: Fe(OH)3(H2O) + H3O+ Fe+(OH)2(H2O)2 + H2OorFe(OH)3(H2O) + H2O Fe+(OH)2(H2O)2 + OH-acidic: Fe(OH)3(H2O) + OH- Fe(OH)4- + H2OorFe(OH)3(H2O) + H2O Fe(OH)4-+ H3O+

Is potassium hydroxide an alka li?
Potassium is a Alkali metal.In order to figure out what the metal is, look at the periodic table. The fist column down contains all the Alkali metals. The second Column down contains all the Alkaline Earth Metals. The Last Column to the right contains all the Nobel gases. The Column before that contains all the Halogens.All above is true...The reason WHY the first column is called the "alkali metals", is that when they react with water they form "alkali" salts (that is... bases.) For example...Potassium + water => potassium hydroxide + hydrogen gasPotassium hydroxide is basic (alkaline).BTW, the alkaline earth metals also for basic salts, but the alkali metals are alot better at it.

Do strong bases dissolve in water?
Only hydroxides of alkali metalsare vrey soluble.
