Sparge water salts

Adding salts to the sparge water has no effect on the water analysis values (residual alkalinity, effective hardness, sulfate/chloride ratio, etc.).

For example, If you add calcium chloride to the mash water, residual alkalinity will decrease, effective hardness will increase, and sulfate/chloride ratio will decrease, as expected. If you add the same calcium chloride to the sparge water you will observe no changes in these values. The same happens with other salts.

I know that residual alkalinity affects mainly the mash. However, salts added to sparge water should be incorporated in sulfate/chloride ratio estimation because this parameter is important for finished beer.
