Question

what are the important pH everyday life short points​

Answer 1

Answer:

Plants and animals are sensitive to pH change

Soil pH and plant growth: Most of the plants grow best when the pH of the soil is close to 7. If the soil is too acidic or basic, the plants grow badly or do not grow at all. ... Chemicals can be added to soil to adjust its pH and make it suitable for growing plants.

$\mathtt{\bf{\large{\underline {\purple{ANSWER:-}}}}}$

➢ The pH plays a vital role in our everyday life. If the pH changes in our mouth it results tooth decay, pH is used in the survival of animals, many plants and animals also use pH for their self defence, and pH is also used in our stomach for the process of digestion.

Let's learn these above examples in detail.

➢ pH change cause tooth decay :-

When we eat sugary food, the bacteria present in our our converts the sugar into acid. This results the decreasing of pH in our mouth and tooth starts decaying (when acid formed in the mouth falls below 5.5). The best way to get rid of this tooth decay is to clean the mouth properly after eating food.

➢ pH change in survival of animals :-

Our body works properly when it has a pH range of 7.0-7.8. If the pH range get disturbed due to some reason, then many heath issues can occur.

➢ pH is used for self defence in some plants and animals :-

There are many plants and animals, like honey bee, wasp, ant, duck and nettle protect themselves from enemies by injecting acids and bases into their skin. Baking soda is applied to it to neutralise the affected area.

➢ pH in our stomach :-

Hydrochloric acid of pH 1.4 is produced in our stomach, which helps in digestion of food. Due to some reason, if acid exceed in our stomach, it causes indigestion. Intake of antacids like magnesium hydroxide and sodium hydroxide can neutralise the reaction.

➢The pH scale was invented in 1909 by sorenson.

➢ The strength of acids and bases are measured through the pH scale.

➢ The pH scale has the value of 0-14 numbers.

➢ According to a pH scale, acids have a pH of less than 7, bases have a pH of more then 7 and neutral of exactly 7.

➢ The pH is also called as an universal indicator.

➢ The colour produced by it, is used to find the pH value of acid and bases.
