how we make acid lake normal again?

Answer 1

If the lake is small and has inflow-outflow rivers, it could be normal again when inflow river has bringed enough clean water.
Elsewhere, there is the "liming": an inletting of tons of calcium carbonate, which reacts with strong acids, releasing carbon dioxide, for example:

CaCO3 + 2HCl → CaCl2 + CO2 + H2O

It worked well with the Lake Maggiore in Piedmont, Italy.

Bye!

Answer 2

OK calculate the volume of the lake,
you the must determine the acid. ( i would make a guess that i carbonic in which case it would naturaly loose its acidity)
then you need to get an alkali and balance it out for example
lake volume= 1000 cubic meters , with a 0.2 molar concentration

OK lets say the acid is HCl {hydrochloric) and you find out it has a molarity of 0.2
so HCl= 1 mole = 36.5 grms of acid.
so in the lake there will be 365/0.2 liters of acid

now you will want to balance it with an alkali for this i will use sodium chloride {NaCl}

NaCl + Hcl= NaH(sodium hydroxide) (s) + Cl2 (g)
what you get is a salt, (like see salt, not harm-full) and chlorine gass.

so you will then need, 585/0.2 liters of NaCl to balance out the lake.



>>>>>>>>>>>>NEW<<<<<<<<<<<
i think that is not 585/0.2 liters, it may just be 58 liters over 0.2

but do not put that amount of alkili in strate away you would have to induce a time plan, depending on the volume of the lake

Answer 3

Dump in a few boxes of baking soda and measure what the PH is . when it gets to PH 7 stop.

Answer 4

with alkaline substances like NaOH

Answer 5

Throw in a couple of antacids...........
