1) Definition of Basicity:
o Basicity refers to the strength of a base, which depends on its ability to donate hydroxide ions (OH−OH^-OH−) in an aqueous solution.
2) Trend in Alkali Metal Hydroxides:
o As we move down Group 1 of the periodic table, the hydroxides of alkali metals become stronger bases due to increased ionic size and solubility in water.
o Order of basicity: CsOH > KOH > NaOH > LiOH.
