The degree of dissociation of a $0.01 \ M$ weak acid is $10^{-3}$. Its $pOH$ is

When a large amount of water is added to a solution of $BiCl_3$,then........

At $298 \, K$,the equivalent conductivity of a $0.01 \, M$ solution of aniline hydrochloride is $122.5 \, \Omega^{-1} \, cm^2 \, eq^{-1}$,but in the presence of a sufficient excess of aniline to prevent hydrolysis,it is $106.5 \, \Omega^{-1} \, cm^2 \, eq^{-1}$. The equivalent conductivity of $HCl$ at infinite dilution is $426.0 \, \Omega^{-1} \, cm^2 \, eq^{-1}$. The hydrolysis constant of aniline is:

The $pH$ of an acidic solution is $4.70$. Calculate the concentration of $OH^-$ ions. $(pK_w = 14)$

What is the concentration of $H_3O^{+}$ ions in a solution having $pOH$ value $9$?

What is the normal $pH$ range of human blood?
