- TL;DR Summary
- Neutralizing acidified lakes
I calculated it and found that is approximately 610Kg needed of CaCO3 to bring the lake pH to a neutral level.Lakes that have been acidified by acid rain can be neutralized
by liming, the addition of limestone (CaCO3). How much
limestone in kilograms is required to completely neutralize
a 3.8e9 L lake with a pH of 5.5? (question credited to Introductory Chemistry Essentials book)
Is my calculation right 1st :)?
Then if this is right, 610kg of CaCO3 is not that much in a matter of cost or weight to help the bio-life of the lake. I'm wondering if we are applying actually this solution? As far as I know, there is no harm to add CaCO3 to water lakes, water is even drinkable with dissolved CaCO3 ions to some extent.
