Acids with Carbonates Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

When an acid reacts with a metal carbonate, what three products are formed?

The reaction makes a salt, water, and carbon dioxide gas.

What is the general word equation for acid reacting with a metal carbonate?

Acid + metal carbonate → salt + water + carbon dioxide.

What visible signs show that an acid is reacting with a metal carbonate?

You see fizzing (bubbles of gas) and the solid carbonate gets smaller or disappears.

What gas is made when an acid reacts with a metal carbonate and how do you test for it?

Carbon dioxide is made. You bubble it through limewater, which turns cloudy if carbon dioxide is present.

What are the products when hydrochloric acid reacts with calcium carbonate?

The products are calcium chloride, water, and carbon dioxide.

What are the products when nitric acid reacts with sodium carbonate?

The products are sodium nitrate, water, and carbon dioxide.

What are the products when sulfuric acid reacts with copper carbonate?

The products are copper sulfate, water, and carbon dioxide.

How do you work out the name of the salt made in an acid and metal carbonate reaction?

The salt’s name comes from the metal in the carbonate and the acid: hydrochloric acid makes chlorides, nitric acid makes nitrates, and sulfuric acid makes sulfates.

Why does the fizzing stop during a reaction between an acid and a metal carbonate?

The fizzing stops when all the metal carbonate has been used up, so no more carbon dioxide gas is made.

Why is a metal carbonate called a base in reactions with acids?

A metal carbonate is a base because it reacts with acids and removes hydrogen ions, forming a salt, water, and carbon dioxide.
