Which alkali metal is most soluble in water?

Which alkali metal is most 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.
What is the order of solubility of carbonates of alkaline earth metal?
BaCO3>CaCO3>SrCO3>MgCO3.
What is the trend of solubility in group 1?
For group 1, ie., Alkali metals, solubility of carbonates in water increases down the group as the decrease in lattice energy is more than the decrease in hydration energy..
Is group 1 carbonate water soluble?
Group 1: Alkali Metals and Carbonates (X2CO3) All except Lithium are soluble in water and stable to heat.
Which of the following hydroxide is most soluble in water?
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 metal hydroxide is most soluble in water?
This is because some magnesium hydroxide has dissolved. Calcium hydroxide solution is referred to as “lime water”. A liter of pure water will dissolve about 1 gram of calcium hydroxide at room temperature….Solubility of the Hydroxides.
Element | Lattice Energy (kJ/mol) | Coordination Number |
---|---|---|
Be | 3620 | 4 |
Mg | 2998 | 6 |
Ca | 2637 | 6 |
Sr | 2474 | 8 |
Which is correct sequence of solubility?
A) Xe>Kr>Ar>Ne>He.
Why solubility of alkali metal carbonates increase down the group?
On moving down the group, their solubility further decreases because their lattice energy remains constant but hydration energy decreases and hydration energy becomes lower than lattice energy. “The solubility of carbonates and bicarbonates of alkali metals increases down the group.”
Are Group 1 metals water soluble?
1. Alkali metal (Group IA) compounds are soluble.
Is Group 1 water soluble?
All compounds of Alkali metal (Group 1, or, Group IA) cations, are soluble. EXCEPT those of calcium, barium and Alkali metal (Group 1, or, Group IA) cations; these soluble ones actually react with the water to form hydroxides (they are said to hydrolyse, and the reaction with water is known as a hydrolysis reaction ).
Are Group 2 carbonates soluble in water?
All the Group 2 carbonates are very sparingly soluble. Magnesium carbonate, for example, has a solubility of about 0.02 g per 100 g of water at room temperature. The trend to lower solubility is, however, broken at the bottom of the group: barium carbonate is slightly more soluble than strontium sulfate.
What carbonates are soluble?
g) All carbonates are insoluble except those of sodium, potassium and ammonium. Magnesium carbonate is slightly soluble. Many hydrogen carbonates, such as Ca(HCO3)2 and Mg(HCO3)2, are soluble.
