Which method is used to prepare sodium nitrate- soluble salt? Tick all that is applicable
Add excess solid reactant to acid
Titration
Precipitation
Why must we add water to prepare the soluble salt: Sodium nitrate?
To make sure the salt is not mixed with any impurities
Because you need to wash the salts with water
It is the next step of the preparation
The salt will not sparkle if not washed
