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
What else can I help you with?
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.
Why is an alkaline subctance dropped in to lakes?
Alkaline substances like lime are sometimes added to lakes to raise the pH levels and neutralize acidic conditions caused by pollution or acid rain. This can help improve water quality, restore natural habitats, and promote the growth of beneficial aquatic organisms.
Can you make lakes less acidic?
Yes, lakes can be made less acidic through a process called liming, where alkaline materials such as limestone are added to neutralize the acidity. This can help buffer the pH levels and improve the overall health of the lake ecosystem. However, it is important to consider the underlying causes of acidity, such as pollution or acid rain, in order to address the root of the issue effectively.
When limestone is added to lakes why is it powdered?
Limestone is powdered when added to lakes to increase its surface area, allowing for quicker dissolution and reaction with acidic water. This helps to neutralize the acidity and restore the pH balance in the lake, promoting healthier aquatic ecosystems.
How do you chemically form table salt?
Sodium and chlorine: it is Sodium Chloride (NaCl).

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.
What happens if you add limestone to acidic lakes?
it stays
Lakes near volcanoes become acidic?
Yes.
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 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.
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.
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.
