The substance added to soils to reduce acidity that starts with l?
Lime Quicklime
What Basic oxide of the type MO used to treat acidic soils?
Lime (CaO) is commonly used to treat acidic soils by neutralizing the acidity, raising the soil pH, and providing calcium for plant growth.

What is dolomite lime?
In horticulture Dolomite lime is added to soils and soil-less potting mixes as an acidity buffer and as a magnesium source
Laterite soils contain high amounts of what?
Laterite soils contain high amounts of iron and aluminum oxides. These soils are typically rich in minerals like kaolinite, quartz, and organic matter, but are poor in plant nutrients due to their high acidity and low fertility.
How did the acidity of the liquid in the beaker change?
The acidity of the liquid in the beaker likely changed due to the addition of an acid or a base, which would alter its pH level. If an acid was added, the pH would decrease, indicating increased acidity. Conversely, if a base was added, the pH would increase, resulting in decreased acidity. Additionally, factors such as temperature or dilution could also affect the acidity of the solution.
What is the difference between forest and prairie soils?
Forest soils tend to be rich in organic matter, have higher acidity, and more microbial activity due to the decomposition of leaf litter and organic debris from trees. Prairie soils, on the other hand, are often characterized by a thicker topsoil layer, higher pH levels, and lower organic matter content, as grasses do not contribute as much organic material as trees.
How acidity occurs?
Acidity occurs when a substance donates hydrogen ions (H⁺) to a solution, increasing the concentration of these ions. This process can happen through the dissolution of acids in water, where they dissociate into H⁺ ions and their corresponding anions. Factors such as the presence of carbon dioxide, organic acids, or certain minerals can also contribute to acidity in natural waters and soils. Overall, acidity is a measure of how acidic a solution is, often represented by its pH level, with lower pH values indicating higher acidity.
What is meant by unproductive soils?
Unproductive soils refer to soils that have poor fertility, low organic matter content, and limited ability to support plant growth. These soils may lack essential nutrients, have a high acidity or alkalinity, or be compacted, restricting root growth and water infiltration. Improving soil health through proper management practices can help make unproductive soils more productive for agriculture or other uses.
Why can ammonia change a flower's color through a flower's pigment?
Ammonia increases the pH of the solution around the flower, which can alter the structure of the pigment molecules in the flower petals. This change in structure can affect the way the pigment molecules interact with light, leading to a shift in the flower's color.
