neutralisation

• What are the products of a neutralization reaction?


  The products of a neutralization reaction are water and a salt.
• What is defined as a neutralization reaction?


  A neutralization reaction is a chemical reaction where an acid and a base react to form water and a salt.
• What role do hydroxide ions (OH⁻) play in neutralization reactions?


  Hydroxide ions (OH⁻) from the base are involved in the reaction.
• What is the pH of a neutral solution?


  A neutral solution has a pH close to 7.
• What are the characteristics of acids?


  Acids produce hydrogen ions (H⁺) in water, have a pH below 7, taste sour, and react with metals.
• What are the characteristics of bases?


  Bases produce hydroxide ions (OH⁻) in water, have a pH above 7, taste bitter, and feel slippery.
• Name two common acids.


  Hydrochloric acid (HCl) and sulfuric acid (H₂SO₄).
• Name two common bases.

  Sodium hydroxide (NaOH) and potassium hydroxide (KOH).
• What happens during the neutralization process?


  Hydrogen ions (H⁺) from the acid combine with hydroxide ions (OH⁻) from the base to form water and a salt.
• What is the chemical representation of a neutralization reaction?


  Acid + Base → Water + Salt.
• What is an example of a neutralization reaction involving hydrochloric acid and sodium hydroxide?


  HCl + NaOH → NaCl + H₂O.
• How do you balance a chemical equation?


  Count atoms on each side and add coefficients to balance the number of each type of atom.
• What is the balanced equation for the neutralization reaction of sulfuric acid and sodium hydroxide?

  H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O.
• What is the balanced equation for the neutralization reaction of nitric acid and potassium hydroxide?


  HNO₃ + KOH → KNO₃ + H₂O.
• What is a real-world application of neutralization reactions?


  Taking antacids to neutralize excess hydrochloric acid in the stomach.
• How does lime affect acidic soil?


  Lime neutralizes acidic soil pH for better plant growth.
• How are neutralization reactions used in industrial processes?


  They are used to treat industrial waste and clean chemical spills.
• What is the effect of taking an antacid tablet?


  It neutralizes excess stomach acid, alleviating symptoms of acid reflux and indigestion.
• What role do pancreatic juices play in neutralization?


  Pancreatic juices neutralize stomach acid to maintain pH balance in the digestive system.
• How do neutralization reactions contribute to pH balance in biological systems?


  They help maintain pH balance by neutralizing excess acids or bases in the body.
