Question

it is around 10.5. that is more basic than baking soda and almost as alkaline as ammonia and bleach. this alkalinity is due to high concentrations of a chemical called natron. natron is a combination of sodium carbonate and naturally occurring baking soda. sodium carbonate is the substance that the ancient egyptians used to dry out mummies! contact with the lake water can cause chemical burns to many animals or people. however, as in many harsh natural conditions, life has found a way to exist in lake natron. in fact, the existence of one species explains why the lake is red. salt - loving red algae thrive in the lake. the salty water is not the only reason why this specific type of algae does well; the algae blooms best when the lake temperature reaches 140°f (60°c). the hotter lake natron gets, the redder it becomes. a toxic type of bacteria exists in the algae blooms, and for most animals, when they eat it, they become very sick. a species of flamingo has adapted to the unusual lake conditions, too. these smaller flamingos have thick skin on their legs that does not get burned in the waters of lake natron. the flamingos get their pink coloration from eating lots of the red algae. what would most likely happen over time if the volcano near lake natron became inactive? the size of the lake would expand. the water would become less alkaline. people would not be able to visit the lake. fewer animals would live on the shores of the lake.

Explanation:

The volcano near Lake Natron contributes to its alkalinity through chemical - related activities. If it became inactive, the source of high alkalinity would be reduced, so the water would become less alkaline.

Answer:

The water would become less alkaline.
