What else can I help you with?
Do insoluble calcium compounds increase the pH of acidic soils eg calcium carbonate and calcium sulfate?
Carbonate will increase soil pH value, because it reacts with acid, but sulfate will not affect the pH.
Is calcium carbonate an acid or a base or a salt?
Calcium carbonate, like other carbonates, is alkaline.
WHAT HAPPENS IF CALCIUM CARBONATE REACTS WITH IRON NAIL?
When calcium carbonate reacts with an iron nail, it typically does not result in a significant chemical reaction under normal conditions. However, if the environment is acidic (for example, in the presence of vinegar), calcium carbonate can dissolve, releasing carbon dioxide gas and potentially leading to some corrosion of the iron due to the acidic conditions. Over time, the presence of acids can lead to rusting of the iron nail, but this is a secondary effect rather than a direct reaction between calcium carbonate and iron.
How does hydrogen peroxide react with an egg shell?
Hydrogen peroxide reacts with the calcium carbonate in an eggshell, which is primarily composed of calcium carbonate (CaCO₃). When hydrogen peroxide is applied to the eggshell, it can break down the calcium carbonate, releasing carbon dioxide gas and forming calcium hydroxide. This reaction can cause the eggshell to bubble and dissolve over time, demonstrating the acidic nature of hydrogen peroxide in contrast to the alkaline properties of calcium carbonate.
Why is calcium carbonate used to neutralize acidic water instead of calcium oxide?
Because if you over correct, excess calcium carbonate is all but harmless, whilst excess sodium hydroxide can be corrosive and toxic.
How is Calcium carbonate used to neutralise acid emissions from power stations?
Calcium carbonate is used in power stations to neutralize acid emissions by reacting with sulfur dioxide and nitrogen oxides in the flue gas. The reaction forms calcium sulfate, calcium nitrate, and water, which are less harmful and can be safely disposed of. This process helps reduce the environmental impact of acid rain caused by these acidic emissions.
Calcium carbonates be used to remove acidic gases from power stations?
Yes, calcium carbonate can be used to remove acidic gases like sulfur dioxide and nitrogen oxides from power station emissions through a process called flue gas desulfurization. This involves the reaction of calcium carbonate with the acidic gases to form less harmful products like calcium sulfate and water.
The acidic ocean water wil erode the calcium carbonate shells true or false?
Yes, it is true that the acidic ocean water will erode the calcium carbonate shells.
How does pH affect the solubility of calcium carbonate?
The solubility of calcium carbonate decreases as pH increases. This is because calcium carbonate is more soluble in acidic conditions and less soluble in basic conditions.
What happens when acidic ground water comes into contact with rock that contain calcium carbonate?
When acidic ground water comes into contact with rock containing calcium carbonate (such as limestone), a chemical reaction occurs. The acidic water dissolves the calcium carbonate, leading to the formation of soluble calcium ions, bicarbonate ions, and carbon dioxide. This process is called chemical weathering and can lead to the erosion and dissolution of the rock over time.
Why calcium carbonate used for farms?
Over time soils on farms become acidic, calcium carbonate is added to fields to regulate the ph of the soil
What happens when you mix acidic water and calcium carbonate?
A calcium salt, carbon dioxide and water are formed.
Is lime deposit acidic or alkaline?
Lime deposits are alkaline in nature. They are typically formed by calcium carbonate, which has an alkaline pH.
Which substance is used in the neutralization of acidic soil?
Lime (calcium carbonate) is commonly used to neutralize acidic soil. Applying lime increases the soil pH, making the soil less acidic and more suitable for plant growth.
Do insoluble calcium compounds increase the pH of acidic soils eg calcium carbonate and calcium sulfate?
Carbonate will increase soil pH value, because it reacts with acid, but sulfate will not affect the pH.
From where does the calcium carbonate that makes a speleothem come?
Calcium carbonate in speleothems comes from the dissolution of limestone or dolomite bedrock by slightly acidic groundwater. This dissolved calcium carbonate is then deposited in caves as stalactites, stalagmites, and other formations through the process of precipitation.
What happens when calcium carbonate reacts with water?
When calcium carbonate reacts with water, it undergoes a chemical reaction to form calcium hydroxide (slaked lime) and releases carbon dioxide gas. This reaction is the basis for the formation of stalactites and stalagmites in caves where calcium carbonate reacts with water dripping from the ceiling.
