thermochemistry heat of neutralisation of strong acid with strong base

When we add a solution of NaOH to the solution of HCl, the pH progressively increases. This is because OH - ions from the base will react with H + ions of the acid to form water. This decreases the concentration of H + ions and therefore pH increases. The pH of the solutio..

Salt of Strong Acid and Strong Base - Here, neither the cation nor the anion undergoes hydrolysis. Therefore, the resulting solution is neutral. For example, aqueous solution of KCl is neutral because when dissolved in water, its ions K + and Cl - have no ten..

An acid, which dissociates completely or almost completely in water, is classified as a strong acid. It must be noted that in these acids all the hydrogen ions (H + ) combine with water molecule and exist as hydronium ions (H 3 O + ). Examples of stron..

The reaction in which an acid and a base react to give a salt and water is called neutralization reaction. Neutralization reactions are exothermic in nature. The heat change when one gram equivalent of an acid is completely neutralised by a ba..

An acid, which dissociates completely or almost completely in water, is classified as a strong acid..

Here, the anion (A - ) is a stronger base than OH - , hence it undergoes hydrolysis to give free OH - ions. Therefore the resulting solution will be basic in character having pH greater than 7. For example Other examples of this type of salts are CH 3 COONa, Na 2 CO 3 , Na 3 PO 4 , et..

This type of titration is carried out between acetic acid and sodium hydroxide. The free H + ion from the weak acid is neutralized by OH - ions from the base and there is a small increase in pH. Around the equivalence point large increase in pH is observed. Howeve..

Here, cation B + undergoes hydrolysis to give free H + ions. Therefore the resulting solution will be acidic in character having pH less than 7. For example, Other examples of this type of salts are NH 4 Cl, CuSO 4 , AlCl 3 , etc. The aqueous solution of a salt of strong ac..

An acid that gets completely or almost completely dissociated or ionised into ions is categorized as a strong acid. Greater the number of hydrogen ions or hydronium ions dissolved in water, the stronger is the acid. For e.g., concentrated (99%) sulphuric ..

A base that dissociates completely or almost completely in water is classified as a strong base. The greater the number of hydroxyl ions the base produces, the stronger is the base. Example..
