What is Real-life Application of Neutralisation?

It is the use of neutralisation reactions to solve everyday problems .

Key Facts and Examples
  • Ant bites inject formic acid into skin .
Example: Red ant bite causes burning pain and swelling
  • Moist baking soda neutralises the acidic effect .
Example: Rubbing baking soda paste reduces ant bite pain
  • Acidic soil prevents plants from growing well .
Example: Crops in acidic soil show yellow leaves, poor growth
  • Lime treatment neutralises acidic soil for better growth .
Example: Farmers add lime powder to improve crop yield
  • Basic soil also harms plant growth .
Example: Plants in basic soil cannot absorb nutrients properly
  • Organic matter releases acids to neutralise basic soil .
Example: Adding compost, manure makes basic soil neutral
  • Factory waste can be acidic and harm water bodies .
Example: Industrial discharge turns lake water acidic, kills fish
  • Basic substances neutralise acidic waste before release .
Example: Adding lime to acidic waste makes it safe
Neutralisation Applications Problem (Acidic) Solution (Basic) Ant bite - formic acid Baking soda - neutralises Acidic soil - poor crops Lime - neutralises soil Factory waste - pollution Basic substances - treat waste

Question (Page Not Specified): When an ant bites, it injects an acidic liquid into the skin. How can this be treated?

Answer:
We have studied that neutralisation reactions occur when acids and bases mix. This is why moist baking soda can treat ant bites .

  • Formic acid from ant bite causes burning sensation
  • Baking soda is basic and neutralises formic acid
  • Neutralisation reduces pain and swelling from bite
Ant Bite Treatment Step 1 - Ant injects Formic acid enters skin Step 2 - Apply base Rub moist baking soda Step 3 - Neutralisation Acid + Base → Salt + Water Pain and swelling reduced!

Question (Page Not Specified): How can acidic soil be treated for better plant growth?

Answer:
We have studied that neutralisation makes acidic substances neutral . This is why lime is added to acidic soil .

  • Acidic soil prevents nutrient absorption by plants
  • Lime is basic and neutralises soil acidity
  • Neutral soil allows better plant growth and crop yield
Soil Treatment Acidic Soil Treatment Acidic Soil + Lime Neutral Soil + Better Growth Basic Soil Treatment Basic Soil + Organic Matter Neutral Soil + Healthy Plants

Question (Page Not Specified): Why is it important to neutralise factory waste before releasing it into water bodies?

Answer:
We have studied that acidic substances can harm living organisms . This is why factory waste must be neutralised .

  • Acidic waste kills fish and water plants
  • Basic substances neutralise the acidic waste
  • Neutral waste is safe for aquatic life
Factory Waste Treatment Effect Before Treatment After Treatment Water nature Acidic - harmful Neutral - safe Fish survival Die from acid Live normally Plant growth Cannot grow Grow healthy Environment Polluted water Clean water
