Question

$pH$ of the solution will be raised by addition of pyridinium ion $C_5{H}_{5}N{H}^{+}$ on the position of the equilibrium.

• A. True
• B. False

Answer 1

The correct option is A True

The effect of the addition of pyridinium ion $C_5{H}_{5}N{H}^{+}$ on the position of the equilibrium , $pH$ will not be raised. Because of the addition of the pyridinium ion, According to Le Chatelier's principle , the addition of $C_5{H}_{5}N{H}^{+}$ will shift the equilibrium to the left, decreasing the $O{H}^{⊝}$ concentration and the $pH$.
