Importance Of pH In Our Daily Life
Plants -:
- Plants cannot grow in highly alkaline or highly acidic soils. Most food crops grow best at a pH of 7-7.8.The growth of plants suffers when the pH value is outside this range.
- If the soil is too acidic then its pH can be raised by adding lime (or slaked lime) which neutralises the excess acid in the soil.
- Similarly, if the soil is too alkaline then its pH can be lowered by adding gypsum or some other substance which can neutralise the excess alkali present in the soil.
Human Beings-:
The pH scale plays a critical role in the human body. Different parts of the human body have different pH.
The mouth has a slightly alkaline pH while the stomach has a very acidic pH. The skin has a slightly acidic pH, and the pH in the Vagina is again very acidic.
- pH in our digestive system
- pH change as the cause of tooth decay
- pH of skin and Vagina.
Acid Rain-:
- When pH of rainwater is less than 5.6, it is called acid rain.
