Making salts with a Soluble Base

Acid + Base → Salt + Water

if the base is soluble, do a TITRATION

• Can’t add excess base, because the base is soluble.
• Can’t filter out excess base.
• Therefore, you must add the base until exactly neutral.

\ The acid that you will use will depend on what salt you want:

• Hydrochloric acid produces chloride salts
• Sulfuric acid produces sulfate salts
• Nitric acid produces nitrate salts

\ \ Making an insoluble salt experiment

• Do the titration WITH an indicator (to find the volume of the base)
• Repeat with NO indicator (left with only base + water)
• Evaporate about half of the solution - until a crystal forms on the end of a glass rod.
• Turn of the heat and let the solution cool.
• Filter off the crystals from the solution.
