C4 - Three Reactions Of Acids

What is a base in chemistry?

A substance that can neutralize an acid to produce a salt and water.

What is an alkali?

A base that is soluble in water.

Give an example of a substance that is a base but not an alkali.

Copper oxide or iron(III) hydroxide.

Give an example of a substance that is both a base and an alkali.

Sodium hydroxide.

What is the general reaction between an acid and a base/alkali?

Acid + Base/Alkali → Salt + Water.

Where does the positive ion in the salt come from?

From the base or alkali (metal ion).

Where does the negative ion in the salt come from?

From the acid.

What type of salt does hydrochloric acid produce?

Chlorides.

What type of salt does sulfuric acid produce?

Sulfates.

What type of salt does nitric acid produce?

Nitrates.

Predict the products of sulfuric acid + zinc oxide.

Zinc sulfate + water.

Predict the products of nitric acid + lithium hydroxide.

Lithium nitrate + water.

What is a metal carbonate?

A compound containing a metal ion and the carbonate ion (CO₃²⁻).

What is the general reaction between an acid and a metal carbonate?

Acid + Metal Carbonate → Salt + Water + Carbon Dioxide.

Predict the products of hydrochloric acid + copper carbonate.

Copper chloride + water + carbon dioxide.

What are the three products when an acid reacts with a metal carbonate?

A salt, water, and carbon dioxide.
