Why does the pH of Coca-Cola change when you place limestone in it?
Coke contains citric acid. The citric acid reacts with the limestone, producing calcium citrate and carbon dioxide (bubbles) and water. The equation below shows the carbonate ion bonding with the acid H on the front of the citrate ion. As the Acid H+1's are removed from the solution, the solution becomes less acid. The pH increases.
2H3C6H5O7 + 3CaCO3 = Ca3(C6H5O6)2 + 3H2CO3(CO2 + H2O)

What is the pH level of limestone?
7.4
Would high pH water weather limestone?
From what I know, limestone is alkali, and high pH water would not weather alkali things. For the case of limestone, it might even make the limestone bigger (think so).
Can limestone be used to lower water PH?
No, lime is a base chemical not an acid compound. Acids lower Ph, base raises Ph. Besides limestone is s stone not lime.
Would limestone raise pH of vinegar?
Yes, because limestone neutralize acetic acid.
What rocks have a pH on the pH scale?
Rocks are mainly salts and have a pH of circa 7. Limestone and dolomite are more basic and have a pH of > 7 but <9.
Reasons for building a limestone quarry?
Well since limestone is a buffer, (meaning it balances the pH of something else) maybe using a limestone quarry would be a good way of creating more limestone:)
Can ants live in crushed limestone?
No, ants cannot live in crushed limestone. Ants don't tend to like limestone and it acts as a deterrent. Furthermore, crushed limestone helps to balance pH levels.
Why do you put manure on limestone soils?
Low pH of the manure counters the high pH of the soil. Acid manure, alkali soil.
