Calculate the degree of ionization of $0.05 \,M$ acetic acid if its $p K_{ a }$ value is $4.74$ 

How is the degree of dissociation affected when its solution also contains $(a)$ $0.01 \,M$ $(b)$ $0.1 \,M$ in $HCl$ ?

$p{K_a}$ of a weak acid is defined as

A weak base $MOH$ of $0.1\, N$ concentration shows a $pH$ value of $9$. What is the  percentage degree of ionisation of the base ? ……$\%$

At $298\,K$  a $0.1 \,M $ $C{H_3}COOH$ solution is $ 1.34\%$  ionized. The ionization constant ${K_a}$ for acetic acid will be

Explain a general step-wise approach to evaluate the $pH$ of the weak electrolyte.
