Question

what are the application of common ions effect​

Answer 1

$\huge{\underline{\underline{\mathfrak{Answer}}}}$

➡️The role that the common ion effect plays in solutions is mostly visible in the decrease of solubility of solids.

➡️Through the addition of common ions, the solubility of a compound generally decreases due to a shift in equilibrium.

➡️The common ion effect also plays a role in the regulation of buffers.

Answer 2

hi mate,

==> Common ion effect is used for the complete precipitation of one of the ions as its sparingly soluble salt with a very low value of solubility product for gravimetric estimation.

==> Ex: Silver ions are precipitated as silver chloride, Barium ions as Barium sulphate, and Ferric ion as Ferric chloride or Ferric sulphate.

==>The common ion effect is the phenomenon in which the addition of an ion common to two solutes causes precipitation or reduces ionization.

==> ... An example of the common ion effect is when sodium chloride (NaCl) is added to a solution of HCl and water.

i hope it helps you.
