S-5.d Neutralisations In Everyday Life

Neutralisations In Everyday Life

Key Notes :

Neutralisation is a chemical reaction between an acid and a base to produce a salt and water.
The general reaction is: Acid + Base → Salt + Water.

Neutralisation is important because it helps to balance pH levels in various environments, making substances safe and suitable for use.

Indigestion Relief: Antacids are used to neutralize excess stomach acid, relieving heartburn.
Soil Treatment: Lime (a base) is added to acidic soil to neutralize it, making it suitable for farming.
Bee Stings: Baking soda (a base) can be applied to a bee sting (acidic) to neutralize the venom and reduce pain.
Wasp Stings: Vinegar (an acid) can neutralize the alkaline sting of a wasp.
Toothpaste: Contains mild bases to neutralize the acids produced by bacteria in the mouth, preventing tooth decay.
Cleaning Products: Many household cleaning products are neutralizing agents that balance acidic or basic residues.

Acid Rain: Limestone (a base) is used in lakes and soils to neutralize the effects of acid rain.

Industrial Waste: Neutralisation is used to treat acidic or basic waste products before they are released into the environment.

Antacids: Medications that neutralize stomach acid to treat conditions like acid reflux and ulcers.
Venom Treatment: Certain antivenoms work by neutralizing the effects of venom from bites or stings.

Cooking: Baking soda (a base) can neutralize the acidity of certain ingredients in recipes.

Preservation: Acids like vinegar are used in food preservation, and neutralization reactions can be used to balance flavors.

pH Indicators: Substances like litmus paper can show when neutralisation has occurred by changing color.

pH Scale: Neutralisation aims to bring the pH closer to 7, which is neutral on the pH scale.
Safety: Ensuring a balanced pH is crucial for safety, comfort, and effectiveness in many everyday activities.
