It turns the acid lake into ph7 neutralising it making drinkable.
Alkali reacts with acid to neutrilise acid, thus, the pH of the acidic lake becomes 7.
An alkali increases the pH of an acidic lake by reacting with hydrogen ions, leading to neutralization and potentially raising the pH closer to 7. This process benefits aquatic life by reducing harmful acidity. Overall, this correction enhances the water quality and supports a healthier ecosystem.
