strength of a solution

Indicators are the chemicals that when added to solutions show whether the solution is acidic or basic, by a sudden change of their colour. The common indicators used and the colour changes observed are mentioned belo..

The strength of acids and bases can be expressed in terms of the concentration of the hydronium ions or hydroxyl ions in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions per litre of solution. This is e..

. Thus the basic character of aliphatic amines should increase with increase of alkyl substitution. In the gasphase, the basic trend in nature is as expected i.e., tertiary amine > secondary amine > primary amine > ammonia. The basic strength in aqueous solution depends not only..

The strength of acids and bases can be expressed in terms of the concentration of the hydronium ions or hydroxyl ions in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions per litre of solution. Thi..

Normality of a solution is defined as the number of gram equivalents (gm.e) of a solute dissolved per litre of the given solution. Mathematically it is, Normality is expressed by the symbol N. It can also be expressed as,..

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 acid behaves like a weak electrolyte, as i..

Summary - Acidic substances generate H + ions in the medium, while basic ones liberate OH - ions in the medium Certain dyes are used as indicators to detect the presence of acids and bases Strength of an acid depends on the concentration of hydronium ions present in a solution. ..

A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystalline. A solid is a crystalline subst..

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 COONH 4 , ..

It is quite clear that the strength of acids and bases can be expressed in terms of the concentration of hydrogen ions, i.e., hydronium ions (H 3 O + ) or hydroxyl ions (OH - ) in a solution. The concentration of hydronium ions in a solution can be expressed as moles..
