This is because at lower pH, the concentration of the anion decreases due to its protonation. This in turn increase the solubility of the salt so that Ksp = Qsp.

The solutions which resist change in pH on dilution or with the addition of small amounts of acid or alkali are called Buffer Solutions.
- Its pH does not change on the addition of small amount of acid or base.
- Its pH does not change on dilution or standing.

9.1. Hydrogen has electronic configuration 1s1similar to the outer electronic configuration (ns1) of alkali metals, which belong to the first group of the periodic table. On the other hand, like halogens (with ns2np5) configuration belonging to the seventeenth group of the periodic table, it is short by one electron to the corresponding noble gas configuration, helium (1s2). Hydrogen, therefore, has a resemblance to both alkali metals, which lose one electron to form unipositive ions, as well as with halogens, which gain one electron to form uni-negative ion. Like alkali metals, hydrogen forms oxides, halides and sulphides. Howeve

It is product of molar concentration of ion raised to the power of number of ions produced per compound in saturated solution.
Solubility of electrolyte decreases due to common ion effect.

Equilibrium is a state at which rate of forwarding reaction is equal to the rate of backward reaction. The equilibrium between ions and unionised molecules is called ionic equilibrium.

A catalyst does not affect the equilibrium composition of a reaction mixture. Catalysts influence the rate of both forward and backward reactions equally.
