Salt Preparation - Lesson 2 Flashcards
Write three names of salts.
Nitric Acid
Sodium Chloride
Calcium Chloride
When making zinc sulfate crystals, what are the chemicals you need?
Zinc Powder
Sulfuric Acid Solution
The first step of making zinc sulfate crystals is…
Use a beaker full of sulfuric acid and add zinc powder. If the reaction is slow you need to heat the solution to make the reaction faster.
The second step of making zinc sulfate crystals is…
Filter the solution through filter paper and a funnel in a conical flask to make zinc sulfate solution.
The third step of making zinc sulfate crystals is…
Boil the zinc sulfate solution in the evaporating dish and heat it to the crystallization point.
The fourth step of making zinc sulfate crystals is…
Leave the crystals to cool.
The fifth step of making zinc sulfate crystals is…
Filter the crystals.
The sixth step of making zinc sulfate crystals is…
Dry the crystals between the filter paper.
Why do you add excess metal?
To make sure all the acid has reacted.
How can you make the reaction faster?
You can heat the solution in order to make the reaction faster.
How do you know that the salt preparation has reached the saturation point?
When the crystal start to form on the side of the evaporating dish.
