The sulfuric acid reacts with the limestone in a neutralization reaction. Limestone: CaCO 3 + H 2 SO 4--> CaSO 4 + H 2 CO 3. The calcium sulfate is soluble in water and hence the limestone dissolves and crumbles. H 2 CO 3--> CO 2 gas + H 2 O. The original acid (hydrogen ions) have been converted to water in these reactions.

Limestone will produce a white powder if it is scratched with a sharp object, due to its soft stone. It also react with acid such as vinegar and hydrochloric acid (HCl) to form a bubble and eventually will neutralize the acid. Varieties of limestone.

When designing and planting your garden, you need to know whether the soil is acid or alkaline, as different plants thrive in different soils. The soil pH is a number that describes how acid or alkaline your soil is. A pH of 7.0 is considered neutral. An acid soil has a pH value below 7.0 and above 7.0 the soil is alkaline.

You can use lime to neutralize the acid in your soil, thus preventing the moss from growing again in the future. Perform a soil test to make sure that your soil is acidic before you treat it with lime. According to Oregon State University, the normal pH for soil is 6.5 to 7. Anything reading below a 6 means you have acidic soil.

As the sulfur dioxide comes into contact with the slurry it is absorbed by the water and the limestone within the slurry neutralises it. The gas that continues to rise is now at a pH level closer to neutral, the slurry then drops back down into the EHT. Any remaining slurry that continues to rise is prevented to pass by a mist eliminator.

In general, bases react with hydrogen ions. This is how neutralization happens. The acid produces hydrogen ions, and the base produces hydroxide ions. These react together to make water. The anion that came from the acid and the cation are left, so if you evaporate the water, you would get a salt. The general reaction looks like this:

In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution. The pH of the neutralized solution depends on the acid strength of the reactants.
