The lake's PH becomes lower or neutral(equal).
when acidic ground water comes in contact with rock that contains calcium carbonate the acidic water starts to dissolve the rock
Calcium carbonate is practically insoluble in pure water; if the rain water is acid calcium carbonate may be dissolved.
Calcium Carbonate
Limestone is calcium carbonate and is basic in nature. When added to dilute acid, limestone will dissolve, forming the corresponding calcium salt, water and carbon dioxide. Eg. 2HCl + CaCO3 ---> CaCl2 + H2O + CO2 or H2SO4 + CaCO3 ---> CaSO4 + H2O + CO2 Note: this is infact one of the major problems of acid rains. When acid rain falls on monuments made up of marbles (which is also another form of calcium carbonate), these monuments fade away as the monuments dissolve slowly.
When u mix calcium chloride&sodium carbonate u get calcium carbonate,which turns lime water milky wen calcium hydrogen trioxocarbonate and sodium chloride i.e cacl2 + Naco3--caco3 +2Nacl.
Limestone is calcium carbonate (CaCO3) which when heated to above 840°C decomposes into calcium oxide (CaO) while releasing carbon dioxide (CO2) according to the equation: CaCO3 → CaO + CO2
Limestone, or calcium carbonate, is entirely harmless in solid form, and exposure will not affect people in any way. However, if you inhale limestone dust, it will irritate the lungs, as does any kind of dust.

When ingested, Calcium Carbonate is generally safe. It is often the inert ingredient in tablets.
It decomposes into calcium oxide and carbon dioxide
