How to prepare a buffer solution using ammonia $(pK_b = 4.75)$? What is the $pH$ of this buffer if the concentrations of ammonia and ammonium chloride are equal?
- AMix equal concentrations of $NH_3$ and $NH_4Cl$; $pH = 9.25$
- BMix equal concentrations of $NH_3$ and $NH_4Cl$; $pH = 4.75$
- CMix $NH_3$ and $HCl$ in $2:1$ ratio; $pH = 9.25$
- DMix $NH_3$ and $HCl$ in $1:2$ ratio; $pH = 4.75$
