Answer to Question #107277 in Inorganic Chemistry for nigel
I have a KCl solution 20g/l with Calcium 500mg/l, I would normally use Na2CO3 to remove the calcium
can potassium carbonate remove calcium hardness from water instead of Sodium Carbonate,
I have a KCl solution 20g/l with Calcium 500mg/l, I would normally use Na2CO3 to remove the calcium
Solution:
yes you can
now as equation goes
2KCl+CaSO4+H2O=K2SO4(aq)+CaCl2
hence 1 mole of K2CO3 reacts with one mole of CaSO4
20g KCl=20/74=0.27 mol
0.5 g CaSO4=0.5/136= 0.00367 mol

interesting... Normally Na2CO3 is added to precipitate Ca as CaCO3 so I was wondering if K2CO3 could be substituted to precipitate CaCO3
