strength of a solution

Summary - Strength of an acid depends on the concentration of hydronium ions present in a solution. Greater the numbers of hydronium ions present, greater is the strength of the acid. A strong acid dissociates completely in water. Example: Hydrochloric acid A weak acid..

Alkaline Earth metals have lesser tendency to react with water to form hydroxides as compared to alkali metals...

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 atmosphere. Osmo..

+ ions in solution, are called weak acids. Example: CH 3 COOH, (COOH) 2 , H 3 PO 4 , HCN, HF, etc. The K a or K 1 values of such acids are much smaller than one. On dilution, the ionization of an acid increases. So, concentration of H + ions also increases on dilution. Therefore, h..

Ionic solids are hard and brittle. Ionic solids dissolve in polar solvents like water "The ions of the ionic solids are pulled out of their lattice sites by the dipole movement of the polar solvent and dispersed into solvent form in the solution. Ionic solids have high melting and boil..

Properties and Uses of Aluminium - 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..

. 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..
