How do you separate barium sulfate formed cleanly when aqueous barium nitrate reacted with aqueous sodium sulfate?
Evaporate the filtrate to saturated solution and allow it to crystallise
Filter to remove barium sulfate
Decant to collect barium sulfate
Distill the barium sulfate
Why is an indicator added in when aqueous sodium hydroxide reacts with nitric acid?
To see the colour changes
To detect the end point in the reaction
To obtained coloured salts
To allow solutions to change colour.
