Silver chloride
Most carbonates
What is an example of making an insoluble salt?
Silver nitrate+sodium chloride > silver chloride+ sodium nitrate
What does silver chloride appear as?
Tiny particles suspended in the solution which is a precipitate
What can you do to the silver chloride precipitate?
It can be filtered, washed and dried in an oven
Is a base insoluble in water?
Yes
What is the process in using a base to create a salt?
Base is added until no more will dissolve
Remove excess to obtain pure solution through filter paper
Water is evaporated to get pure salt crystals
What method is used for alkali used to make a salt?
Titration
What is it called when a substance is added until no more will dissolve?
An excess
How is titration used to obtain a salt?
The method is done without using universal indicator
What is the method of titration?
The acid with universal indicator is added to the alkali until it has made an appropriate colour change
