The main differences between solubility product and ionic product are given as under: Solubility product Ionic product Solubility product is the concentration of ions of electrolyte, each raised to the…
The solution which resists changes in the hydrogen ion concentration on the addition of small amount of acid or base is known as buffer solution. Many medical and cosmetic formulations…
We know that weak acids and weak bases slightly ionize in water and equilibrium is established in their solutions. The phenomenon of suppression of the degree of dissociation of a…
Buffer action: the ability of the buffer solution to resist the changes in pH value on the addition of small amount of an acid or a base is known as…
We can derive a general equation for calculating the pH of any buffer solution. Consider a mixture of weak acid (HX) and its conjugate base. HX + H2O ⇌ H3O+…
In this case, neither the cations nor the anion undergoes hydrolysis. Therefore, the solution remains neutral. For example: in the aqueous solution of NaCl, its ions Na+ and Cl– ions…
Buffer capacity is defined as the rate of change of pH with number of moles of acid or base added. Buffer capacity = dpH / dn acid or base dpH…
According to Henderson – Hasselbalch equation: pOH = pKb + log (/ ) pKb = – log Kb = – log .85 x 10-5 = 4.733 Therefore, pOH = 4.733…
In physical chemistry, there is always a need to measure physical quantities and these measurements involves a numerical ratio between two samples of quantity; one which has to be measured…
With scientific research going all over the world, the communication is very important. This communication becomes very easy if there is an agreement on international level regarding the use of…
