Ionic Equilibrium question

2025 · 23 Jan · Shift 1 · Q23

JEE MainChemistryIonic EquilibriumNumerical+4 / −1
If 1 mM solution of ethylamine produces pH=9\mathrm{pH}=9pH=9, then the ionization constant (Kb)\left(\mathrm{K}_{\mathrm{b}}\right)(Kb​) of ethylamine is 10−x10^{-x}10−x. The value of xxx is ‾\underline{\hspace{2cm}}​ (nearest integer). [The degree of ionization of ethylamine can be neglected with respect to unity.]
