Because over use of NaOH may make the lake alkaline.
So magnesium carbonate or calcium carbonate are used.
Remember carbonates react with acids to produce a salt, water and carbon dioxide.
HCl + NaOH = H2O + Na^+ ( Alkaline) + Cl^-
HCl + CaCO3 = CaCl2(aq) [salt] + H2O + CO2

Can you make lakes less acidic?
Don't cause pollution!
Where is the element sodium usually found in the world?
The element sodium is present in the sea in the compound sodium chloride(NaCl) or salt. Also soda lakes like lake Bogoria in the Great rift valley contain very high amounts of sodium hence the name soda lakes.
Why might adding calcium carbonate or sodium carbonate to acidic lakes solve the problem?
Sodium Carbonate (NACO3) and Calcium Carbonate (CACO3) are alkaline salts which neutralises the acidity of a lake. Also, once an acid is neutralized, the remaining alkaline substances will create hydroxyde OH- ions which helps elevate the pH over 7.
How does acid rain affect life in water?
As acid rain is acidic in nature it will change the pH of lakes and rivers also which will affect the aquatic life in them
Why scientists might monitor pH value of rivers and lakes?
Scientist may monitor pH value of rivers and lakes to protect aquatic animalslike fishes etc. If the pH is too low it indicates that the water is acidic and it will cause the death of fishes.
Why is powdered limestone sometimes deliberately added to lakes in countries like Norway and Sweden?
if the water is too acidic the limestone will react to help neutralize the acid.
Why is lime added to acidic lakes?
Lime is a strong base. When you add a base to an acid it turns it neutral. So by adding the lime to the water after a while it'll turn into precipitation itself and neutralize the acid. This is also known as acid-base neutralization.
Do lakes near volcanoes become acidic?
Yes.
Lakes near volcanoes become acidic?
Yes.
What happens if you add limestone to acidic lakes?
it stays
Can you make lakes less acidic?

What contributes most to acidic conditions in lakes?
The emissions that are let out into the environment is the main contributor to acidic conditions in lakes. When these toxins are let out into the air they get absorbed into the clouds. When it rains the rain drops deposit the acids from the toxins into the lakes and water ways.
Why are lakes limed?
Lakes are limed because of acid rain, without the added alkali in the water the pH balance of the lake would be pushed further towards acidic and this would be very detrimental to the aquatic life which have quite narrow tolerance bands for pH. So to keep the pH at roughly the same level lime is added.
What chemical can be added to lakes to make them less acidic?
Limestone chips
How does water in ponds and lakes become acidic?
Ponds and lakes become acidic via acid rain when the CO2 rises into the atmosphere and is absorbed and then when it falls back onto the earths surface it can runoff into ponds and lakes usually being accompanied by things such as weed killers and human waste therefore its acidity becomes more concentrated therefore when it finally enters the lakes or ponds in large quantities it causes the lakes and ponds acidic levels to change.
What is the uses of sodium chloride?
Some important applications of sodium chloride - seasoning for foods- preservative for foods- preparation of sodium, chlorine, sodium hydroxide, hydrogen- roads deicing- soaps fabrication- salts baths- saline solutions and other applications in medicine Also: - sodium is indispensable for life - mine salts are touristic attractions - saline lakes are used for treatments or fun - the salt tracks are frequently used for auto or moto eventsetc.
Whew can you find sodium?
in oceanor salt lakes
