प्रश्न
Explain the pH scale with the proper diagram.
उत्तर
- pH helps in measuring hydrogen ion concentration in solutions. In pH, p stands for “potenz” means “strength” in German.
- The scale reads from O (zero) (most acidic) to 14 (most basic).
- The value of pH indicates the acidic or basic nature of a solution. The strength of the base is represented by pOH.
- When the pH value is between 0 to 7, the solution is acidic in nature. At value 7, the solution is neutral and between 7 to 14 the nature of the solution becomes alkaline/ basic.
- Lower the pH of an acid, greater is the concentration of H+ ions, greater the pH of a base, greater is the concentration of OH ions.

Frothing in Yamuna:
The primary reason behind the formation of the toxic foam is the high phosphate content in the wastewater because of detergents used in dyeing industries, dhobi ghats, and households. Yamuna's pollution level is so bad that parts of it have been labelled 'dead' as there is no oxygen in it for aquatic life to survive.
Predict the pH value of the water of river Yamuna if the reason for froth is the high content of detergents dissolved in it.
