Hydrates

Question 1

Hydrates

Answer 1

Ionic compounds that have a definite ratio of water and salt

Question 2

Hydrates are made up of what two compounds?

Answer 2

Anhydrous salt and water

Question 3

Formula of a hydrate

Answer 3

Anhydrous salt X (times) number of water hydrate

Question 4

How can you identify when a substance is a hydrate?

Answer 4

You know when a substance is a hydrate when there is an equal ratio between the water and salt

Question 5

What is the difference between a hydrate and its anhydrous form?

Answer 5

A hydrate has water trapped inside of it meanwhile the anhydrous form is just salt and no water.

Question 6

How do Hydrates make anhydrous salts?

Answer 6

When Hydrates are heated, the water releases vapor. The remaining is the anhydrous salt.

Question 7

Anhydrous equation?

Answer 7

anhydrous salt + water –> hydrate
hydrate –> (heat) water + anhydrous salt

Question 8

Relationship between hydrates and its anhydrous salt?

Answer 8

A hydrate has water molecules in between the actual salt. The anhydrous salt is the form taken when those hydrates are heated (creating crystals)

Question 9

How is copper (II) sulfate different from its hydrate copper (II) sulfate pentahydrate?

Answer 9

It is different because its hydrate has water added in between the molecules. Copper (II) sulfate is simply just salt.

Question 10

Percent H2O/composition

Answer 10

part/whole x 100
