lewis acids and bases proton

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..

The heat of neutralization of a weak acid or a weak base is less than -57.1 kJ and is also different for different weak acids or bases. For example for acetic acid the enthalpy of neutralization is -54.9 kJ. This can be explained as follows: Acetic..

The amino acids that are to be supplied through diet are called as essential amino acids. They cannot be produced by the body. The essential amino acids are arginine, valine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine and tryptop..

Question 1 - Question: Define the terms: Acid, alkali and salt. Answer: An acid is a compound, which releases hydronium ions (H 3 O + ) as the only positive ions in solution. An alkali is a compound, which releases hydroxyl ions (OH - ) as the only negative ions in solution. A s..

In this case both the cation and anion undergo hydrolysis to the same or different extents. The resulting solution may be neutral, acidic or basic depending upon the relative strengths of acids and bases. The hydrolysis may be written as: Some common examples are CH 3 ..

Salt of Weak Acid and a Weak Base - In this case both the cation and anion undergo hydrolysis to the same or different extents. The resulting solution may be neutral, acidic or basic depending upon the relative strengths of acids and bases. The hydr..

Salt of a Strong Acid and Weak Base - 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 mechanism of acid-base indicator was developed by Ostwald, which offered an explanation for the colour change with change in pH. All acid-base indicators are weak organic acids or bases, which possess different colours in unionized and ionized states. If..
