Edexcel IAL Chemistry AS 8.SP5 Water of crystallisation by titration
Edexcel IAL Chemistry AS 8.SP5 Water of crystallisation by titration
Work backwards from the titre through dilution and reaction ratios, find the anhydrous salt mass and divide the remaining water moles by salt moles.
How this is tested
- Find hydrated-salt moles from direct titre or acid remaining after back titration.
- Calculate water moles from the mass difference and determine the integer hydration value.
