Acid Base reactions | Class 10 Chemistry #3

TL;DR

Acid-base reactions involve the combination of acid and base to form a neutral salt, and these reactions can also involve metals, metal oxides, metal carbonates, and metal bicarbonates. Copper vessels should not be used to store pickles due to the reaction between copper and acid.

Transcript

you may have heard this from your mom or your grandma that never store pickles in copper vessels why that's because copper reacts with acid to form poisonous metal oxides so you may ask where is acid pickle has lemon in it and lemon has citric acid so here we are talking about a reaction between a metal and an acid hello friend so i am back here wi...

Questions & Answers

Q: Why should pickles not be stored in copper vessels?

Copper reacts with the acid in pickles to form poisonous metal oxides, making it unsafe for consumption.

Q: How do acids and bases react with each other?

In a neutralization reaction, acids and bases combine to form a salt and neutralize each other's effects, resulting in a neutral solution.

Q: How do acids react with metals?

Acids react with metals to form a salt and hydrogen gas. The reactivity depends on the position of the metal in the reactivity series, with more reactive metals displacing hydrogen from the acid.

Q: Do all bases react with metals?

No, only certain metals like zinc and aluminum react with bases to form a salt and hydrogen gas. Most bases do not react with metals.

Q: What happens when metal carbonates react with acids?

Metal carbonates react with acids to form a salt, carbon dioxide, and water. The specific salt formed depends on the metal and acid used.

Q: How do metal oxides react with acids?

Metal oxides react with acids to form a salt and water. The oxide acts as a base during the reaction.

Q: Do non-metallic oxides react with bases?

Yes, non-metallic oxides, such as carbon dioxide, can react with bases to form a salt and water. The oxide acts as an acid during the reaction.

Q: Which metals are exceptions and react with both acids and bases?

Zinc and aluminum are examples of metals that react with both acids and bases. They are called amphoteric because they can exhibit both acidic and basic properties.

Summary & Key Takeaways

  • Acids and bases react with each other in a neutralization reaction, forming a salt and neutralizing each other's effects.

  • Acids react with metals to form a salt and hydrogen gas, with the reactivity depending on the position of the metal in the reactivity series.

  • Bases react with certain metals, such as zinc and aluminum, to form a salt and hydrogen gas.

  • Metal carbonates and bicarbonates react with acids to form a salt, carbon dioxide, and water.

  • Metal oxides react with acids to form a salt and water.

  • Non-metallic oxides, such as carbon dioxide, react with bases to form a salt and water.
