strength of a solution

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 hydrolysis may be written as: Some..

The modern process for the manufacture of H 2 O 2 is based on the autoxidation of 2-ethylanthraquinol. This method, involves alternate oxidation and reduction steps of 2-ethylanthraquinol. In this process, a 10 per cent solution of the compound is prepared in a mixture of benzene and an..

Some Interesting Features - Plants wilt when turgor pressure inside the cells of such tissues go down below zero. Pressure chamber is used for measuring water potential of whole leaves, shoots, etc. The value of osmotic pressure of the soil solution in a well watered soil is less than one..

Hydrogen peroxide can be prepared on a large scale by the electrolysis of ammonium hydrogen sulphate dissolved in excess of sulphuric acid, using platinum electrodes and a high current density. In order to have high current density (i.e., current strength per unit area of the electrode) ..

1. Aluminium is a light silvery-white metal with high tensile strength, a high electrical and thermal conductivity. On a weight-to-weight basis, the electrical conductivity of aluminium is twice that of copper. 2. It is highly electropositive and readily reacts with oxygen to form a hard ..

. Thus bond strengths of the compounds decrease as we move down the group. For example, lithium has relatively high heat of atomization, melting and boiling points, density and hardness. The first member will have a higher electronegativity than other group members and shows greater prope..

. The presence of substitutents in the aromatic ring effects the acid strength of phenols. Election withdrawing groups in ortho and para positions increase acid strength and electron - releasing groups decrease it. Alcohols undergo nucleophilic substitution with hydrogen halides..
