Which is the weakest base among NaOH CA OH 2 Koh and be oh 2?
Be(OH)2is the weakest base, since alkali metal hydroxides are stronger base than alkaline earth metal hydroxides. Also, basic character of hydroxides increases on moving down the group. Hence, Be(OH)2 is the weakest base.
Why are NaOH or KOH not used instead of Ca Oh 2?
Look at charge Na has +1 charge and Ca has +2 charge after dissociation . Greater charge Stronger lattice. And as we need weak Lattice, so NaoH is stronger base than Ca(OH)2..
Why is calcium hydroxide Ca OH 2 S insoluble in water but sodium hydroxide NaOH is soluble?
b) The solid NaOH dissolves in water to produce Na+ ions. These ions reduce the solubility of the Ca(OH)2, since there are less available water molecules to hydrate the calcium hydroxide. Therefore the calcium hydroxide solubility is reduced.
Which is the weakest base among NaOH CA OH 2 KOH and Zn OH 2 NaOH KOH CA OH 2 Zn OH 2?
Answer: zinc hydroxide is the weakest among all these bases as it is less reactive.
Which is stronger base OH 2 or KOH?
koh is stronger base than caoh. Explanation: the ionsisation enthalpy decreases down the group, therefore the basic strength of hydroxides increases. Hence, KOH is stronger base than ca(oh).

Is Ca(OH)2 a strong base?
Ca (OH)2, Mg (OH)2, NaOH and KOH are all “strong bases”, but one is “slightly soluble” in water. Which one is it and why? It is easy to state which ones are most certainly very water soluble. Both NaOH and KOH are highly water soluble. NaOH will dissolve to the extent of 1110 g/L at 20º C, KOH is pretty similar at 1210 g/L at 25º C.
Which compound is more soluble in water Ba(OH)2 or NaOH?
More ionic a compound is ,more soluble it will be in water . So extent of solubility of Ba (OH)2 will be more . Ca (OH)2, Mg (OH)2, NaOH and KOH are all “strong bases”, but one is “slightly soluble” in water. Which one is it and why? It is easy to state which ones are most certainly very water soluble. Both NaOH and KOH are highly water soluble.
Are NaOH and Koh soluble in water?
Both NaOH and KOH are highly water soluble. NaOH will dissolve to the extent of 1110 g/L at 20º C, KOH is pretty similar at 1210 g/L at 25º C. Now, for the other two. Neither of them is very soluble.
Why is Mg(OH)2 not considered a strong base?
In addition, Ca (OH)2, Sr (OH)2 and Ba (OH)2 are said to be strong bases. They are not very soluble in water, but what does dissolve dissociates completely. Not so for Mg (OH)2. Therefore, Mg (OH)2 is not considered a strong base. Calcium hydroxide (Ca (OH) 2) is a strong base.
