Which of the following produces relatively few ions in solution?
NaOH
Ca(OH)\(_2\)
KOH
AI(OH)\(_3\)
Paskaidrojums
Aluminium hydroxide is not soluble in water because it is polymeric and it also has high lattice energy and therefore it is hard to break bonds in this compound. So, water cannot dissolve such types of compounds.
Al(OH)\(_3\) is not soluble in water
