The way to fix this acidic lake was to add calcium carbonate since it had vast neutralization properties and would cause the acid and base to be equal. Conclusion To conclude, to balance the lake’s acidity it had to be “limed”. This means the addition of a basic solution to the acidic lake caused the lake to become neutralized. A neutralized pH could only be achieved if there was an equal amount of proton donors and proton fix this issue permanently, a solution would be to reduce the amount of pollution released from the coal power plant by installing a cleaning technology.
