Neutralization reaction A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.

Q Define Neutralization reaction. The reaction of an acid with a base to form a salt and water is called neutralization reaction. Example: NaOH + HCI NaCI + H2O ACID BASE It is a substance that ionize in water to produce H+ ions. It is a substance that ionize in water to produce OH- ions.
Naming The reaction gets its name because the acid and the base cancel out each others properties to produce a solution which is neutral i.e. It is neither acidic nor basic.
Importance Antacid medicines Cleaning products Water treatment Food and drink Preventing tooth decay
1. Antacid Treating acidity and ingestion. Examples 1. Tums 2. Pepto-Bismol Helpful: 1. Neutralize excess stomach acid惠慍悋惡 擧悋 惺惆 . 2. Relieve 惆悋 愕擧 discomfort悛惘悋 惡 . Tums and Pepto- Bismol are alkaline compunds Having the properties of an alkali or alkali metals.
2. Cleaning product Acidic or basic. Work by neutralizing the pH of the surface. Examples Cleaning 1. Vinegar (Acetic Acid) Bathroom tiles that are alkaline 2. Baking Soda ( Sodium bicarbonate) Acidic surfaces of kitchen counters. * pH tells quantitative measure of the acidity or basicity of aqueous solutions.
3. Water treatment To balance pH of water. Problems If water is too acidic or basic. 1. Corrosion of pipes. 擧拗悋悗 擧悋 拆悋悧拆攤 2. Skin irritation悴 擧 悴惆
4. Food and drink Production of food and drink products. Examples Used Function Baking Soda Baking Neutralize acidity of Vinegar and buttermilk Citric Soft drinks Sour taste
5.Preventing tooth decay擧悋 惆悋惠 愕悋 Tooth decay is caused by the acids produced by bacteria in the mouth, which can dissolve the mineral content 惺惆 悋惆 of the enamel, leading 愀惘 擧 to cavities. When we consume悋愕惠惺悋 acidic foods and drinks, the pH of the mouth drops and making it more acidic惠慍悋惡 This acidic environment promote惆悋 惘愃 the growth of bacteria that produces acids, leading to tooth decay. However , the pH of the mouth can be neutralized by the alkaline compounds found in saliva惠攵擧 and certain foods, which help to prevent 惘擧悋tooth decay.
Example When we eat foods that are high in calcium and phosphate, such as cheese and milk, these minerals can neutralize the acids in the mouth, helping to prevent tooth decay. Similarly, chewing sugar-free gum can stimulate saliva 惠攵擧 production, which can help to neutralize the acids in the mouth and wash away food particles and bacteria.
Dental treatments Fluoride therapy and remineralizing agents work by neutralizing the acids in the mouth and promoting the formation of new mineral crystals in the tooth enamel, which can help to prevent tooth decay. Fluoride therapy Fluoride Amorphous calcium phosphate (ACP) Arginine
Conclusion Overall, neutralization reaction play a key role in preventing tooth decay by neutralizing the acids in the mouth and promoting惆悋 惘愃 the growth of healthy tooth enamel.
