Collect information about importance of ph value in daily life to human beings as well as plants

Answer 1

There is lot of importance of pH in everyday life of an human being as well as plants :

The value of the pH for the human body is in the range of 7 to 7.8. This range shows the importance of pH in everyday life which makes an important statement about the kind of environment we would like to be in. 
The pH of the rain water could also be measured and it is experimentally found that most of the rainfall for the first 10 -15 minutes is acidic in nature. If the value of the pH is found to be less than the value 5.6 then the rain is thought to be acidic. Acidic rains is highly damaging in nature.
The acidic rain effect is evident for architectural marvel of the world the Taj Mahal. The main cause of this is the Mathura Oil refinery and many of the factories that has come up in the vicinity of Taj.The air in the surrounding areas are polluted and are filled with gaseous particles responsible for such type of rain. This type of rain could cause damage to the crops as well and change the pH of crop field soil profile.
Even in our digestive system, particularly the stomach, contains digestive juices or acids that help in the process of digestion and since the process of digestion is very important one the pH plays a big role in maintaining the neutral atmosphere of the stomach.
During this process of digestion a lot of acids are also secreted in the stomach. These acids if not neurtralised on time could damage the inner linings of the stomach and food pipe as well. 
To neutralize the acids that are produced, some bases needs to be added. These bases are taken externally in the form of tablets and syrups which are basically nothing but diluted form alkaline suspension like milk of magnesia. 
So, the importance of pH in everyday life is immense. The presence of pH in mouth is also important. This pH value is roughly around 5.5. Once the food is taken in and pushed through food pipe there are still some particles of food remaining in the mouth cavity. 
The bacteria present in the mouth starts breaking down these food particles and while doing so produce acids which usually damage the teeth or trigger the teeth decay teeth.The human teeth are made up of a material that is the hardest in nature, and is not corroded by any substance. But when these teeth are exposed to the acids generated by the bacteria they are prone to tooth decay. 
This can be prevented if one is a bit careful. Wash and rinse mouth thoroughly after taking food. Mouth wash could also be used. The teeth can be brushed twice a day and this helps a lot in preventing the tooth decay. In order to neutralise the effect of mouth cavity acid build up the tooth pastes are found to be basic in nature.

 

Answer 2

Answer:

scale for measuring hydrogen higher concentration in a solution called pH scale has been developed the p in pH stand for potential means meaning power which with the happiest scale we can measure period from zero to 14 the importance of PH in our everyday life as follows-

(1) plants and animals are pH sensitive-our body works within the pH range of 7.0 to 7.8 leaving organs can survive only in a definite range of PH when pH of plane water is less than 5.6 it is called acid rain when water of acid rain flows into the river it lowers the pH of the river water the survival of aquatic life in such rivers become difficult

(2) importance ine healthy growth of plants-plants require a specific pH range for their healthy growth so pH of soil from various places is determined and then it is treated accordingly when the soil is more acidic than lime is mixed in it and then it is basic then acid substance is mixed to maintain proper PH

(3) importance in digestive system-pH is also important in our resistance system are stomach produces hydrochloric acid it helps in the digestion of food without having the stomach during the digestion the stomach produces too much acid and this causes pain and irritation in stomach to get rid of this pain basis called antacids are used these and this is nutrilize the access of magnesium hydroxide amide base is often used for this purpose

(4) tooth decay due to change in pH-tooth decay stars when the pH of the mouth his lower than 5.5 tooth enable made up of calcium phosphate is the hardest substance in the body it does not dissolve mouth is below 5.5 bacteria present in the north produce acid by degradation of sugar and food particles remaining in the mouth after eating to prevent this mouth should be clean after eating food using toothpaste which are generally basic for cleaning the date can neutralize the axis acid and prevent tooth decay

(5) self defence by chemical produced by animals and plants-be sting leaves and acid which causes pain and irritation uses of a mild base like baking soda on the 10 area gives relief stinging here of metal leaves inject methanoic acid causing burning pain at traditional Amity is rubbing the area with their leaf of the dock plant
