Question Description
pH is quite useful to us in a number of ways in daily life. Some of its applications are:Control of pH of the soil: Plants need a specific pH range for proper growth. The soil may be acidic, basic or neutral depending upon the relative concentration of H* and OH-. The pH of any soil can be determined by using pH paper. If the soil is too acidic, it can be corrected by adding lime to it. If the soil is too basic, it can be corrected by adding organic manure which contains acidic materials.Regaining shine of a tarnished copper vessel by use of acids: A copper vessel gets tarnished due to formation of an oxide layer on its surface. On rubbing lenion on the vessel, the surface is cleaned and the vessel begins to shine again. This is due to the fact that copper oxide is basic in nature, which reacts with the acid (citric acid) present in lemon to form a salt (copper citrate) which is washed away with water. As a result, the layer of copper oxide is removed from the surface of the vessel and the shining surface is exposed.Self-defence by animals through chemical warfare: Stings of bees and ants contain methanoic acid. When stung, it causes lot of pain and irritation. This can be cured by rubbing the affected area with mild base like baking soda.Q. P is an aqueous solution of acid and Q is an aqueous solution of base. When these two are diluted separately, thena)pH of P increases while that of Q decreases till neutralisation.b)pH of P decreases while that of Q increases till neutralisation.c)pH of both P and Q decrease.d)pH of both P and Q increase.Correct answer is option 'A'.
