Flashcards in acids and bases Deck (13):
1

What is a salt?

A salt is any compound formed by the neutralisation of an acid by a base.

2

Where do the 2 parts of the salts name come from?

The first part comes from the metal, metal oxide or metal carbonate. The second part comes from the acid.

3

What salts does nitric acid produce?

Nitrate salts

4

What salts does hydrochloric acid produce?

Chloride salts

5

What salts does sulfuric acid produce?

Sulfate salts

6

If sodium hydroxide reacts with hydrochloric acid, what salt will it produce.

Sodium Chloride.

7

If zinc oxide reacts with sulfuric acid, what salt will it produce.

Zinc Sulfate

8

How do you make an insoluble salt?

To make an insoluble salt, two soluble salts need to react together in a precipitation reaction.

9

How do you make a soluble salt?

Soluble salts can be made by reacting acids with either soluble or insoluble bases.

10

What are the 3 main types of bases?

Metal oxides, Metal hydroxides (alkali) and metal carbonates.

11

What are the general word equations for each type of base when neutralising an acid?

1) Acid + metal oxide = salt + water
2) Acid + metal hydroxide = salt + water
(acid + alkali = salt + water)
3) Acid + metal carbonate = salt + water + carbon dioxide

12

What is a base?

A base is a substance that neutralises an acid. An alkali is a soluble base.

13

What is the word equation for potassium hydroxide and nitric acid?

Potassium hydroxide + nitric acid = Potassium nitrate + water
