How strong are acid or base solutions, pH scale, application of pH scale
How strong are acid or base solutions? Acid-base indicators are used to distinguish between and acid and a base. A scale for measuring the hydrogen ion concentration in a solution is known as pH scale. pH is a scale which is used to specify the acidity or basicity of an aqueous solution. pH scale is logarithmic. The p in pH stands for Potenz in German which means that power. And it is inversely indicates the concentration of hydrogen ion in the solution. On the pH scale , pH is generally measure from 0 (very acidic) to 14 (very alkaline). The higher the hydronium ion concentration , the lower is the pH value. The solution with the pH value are neutral solution. Example:-- water. The neutral value of the pH value depends on the temperature. The solution with pH less than 7 are acidic solution. The pH value can be less than 0 for very strong acids. The solution with pH value greater than the 7 are basic solution. The pH value can be more than the 14 fo...
