Which alkaline earth metal hydroxide is most soluble?
The hydroxides of the alkali metals, lithium, sodium, potassium, rubidium, and cesium, are the strongest bases and the most stable and most soluble of the hydroxides. Sodium hydroxide, NaOH, also known as caustic soda or lye, is of great industrial importance.
Which alkaline earth metal hydroxide is least soluble in water?
Which of the following alkali-metal hydroxides is the least soluble in water? Except lithium hydroxide,all the alkali metal hydroxides are highly soluble in water. LiOH is much less soluble on account of high lattice enthalpy.
Why is alkaline earth metal hydroxide soluble?
Among alkaline earth metal hydroxides, the anion being common, the cationic radius will influence the lattice enthalpy. Since lattice enthalpy decreases much more than the hydration enthalpy with increasing ionic size, the solubility increases down the group (↓).
Why does the solubility of alkaline earth metal hydroxide increases down the group?
So, the solubility of alkali metal hydroxides increases down the group. This is due to the decrease in lattice energy of the hydroxide salt(in case of hydroxides) and the size of the cation increases down the group. Hence, option (c) is incorrect. -Sulphates of this group, their solubility decreases down the group.
Which is the least soluble alkali?
LiF is the least soluble among the fluorides of alkali metals.
Which of the following alkaline earth metal hydroxide is the least?
Be(OH)2 is least basic. Down the group basicity of hydroxide increases. Q3. Metals from basic hydroxides.
Which alkaline earth metal hydroxide is soluble in NaOH?
List of metal hydroxides solubility with colours
| Metal hydroxide | Solubility | Colour of solid state |
|---|---|---|
| NaOH | soluble | white |
| KOH | soluble | white |
| Be(OH)2 | insoluble | white |
| Mg(OH)2 | insoluble | white |
Is BA OH 2 the most soluble in water?
The oxides of calcium, strontium, and barium are basic and the hydroxides are strongly basic. The solubilities of the hydroxides in water follow the order: Be(OH)2 < Mg(OH)2 < Ca(OH)2 < Sr(OH)2 < Ba(OH)2.
Why does solubility of alkaline earth metals decrease down the group?
Why Solubility of Alkaline Earth Metals decreases down the Group? Beryllium ion is the most soluble and the solubility decreases with increasing size so that Barium ion is the least water-soluble alkaline earth metal ion. Solubility in water is related to the ionic nature and size.
What are the chemical properties of alkaline earth metals?
Chemical Properties of Alkaline Earth Metals. 1 Hydrides. Beryllium does not react with hydrogen directly. Beryllium hydride can be prepared by the reduction of beryllium chloride with lithium 2 Reaction of Alkaline Earth Metals with Water. 3 Carbides. 4 Oxides. 5 Hydroxides.
What happens when solubility of metal hydroxide is high?
When solubility of metal hydroxide in water is high, it gives a good alkaline solution due to complete dissociation of metal hydroxide compound for releasing of hydroxyl ions (OH -) into the water. All alkali metals hydroxides are soluble in water. An error occurred.
Why does metal hydroxide react with both acids and alkalis?
Some metal hydroxides are amphoteric compounds and they react with both acids and alkalis to give soluble compounds. When solubility of metal hydroxide in water is high, it gives a good alkaline solution due to complete dissociation of metal hydroxide compound for releasing of hydroxyl ions (OH -) into the water.
