Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.
What else can I help you with?
Two elements found in hard water?
Typicall water hardness is caused from calcium and magnesium compounds dissolved in the water. The term "hard water" is used to describe water that has a high mineral content, usually calcium and magnesium in the form of carbonates, but may include several other metals as well as bicarbonates and sulfates, (water with a low mineral content is known as soft water). A high enough concentration of these metals in your water can cause white lime scales on surfaces which the water comes into contact with. Total water 'hardness' is reported as ppm w/v (or mg/L) of calcium carbonate (CaCO3). Water hardness usually measures the total concentration of calcium and magnesium, the two most common metal ions, although in some locations around the world iron, aluminium, and manganese may also be present at elevated levels. Calcium usually enters the water as either calcium carbonate (CaCO3), from limestone or chalk, or from mineral deposits of calcium sulfate (CaSO4).
Permanent hardness of water due to?
Permanent hardness of water is typically caused by the presence of calcium sulfate (CaSO4) and magnesium sulfate (MgSO4) in the water. These minerals do not precipitate out of solution when water is boiled, unlike temporary hardness caused by calcium bicarbonate which can be easily removed by boiling. Permanent hardness can be removed through processes like ion exchange or chemical precipitation.
Water hardness due to?
Water hardness is due to high levels of minerals, primarily calcium and magnesium, present in the water. These minerals can accumulate in water sources through contact with rocks and soil, leading to increased hardness. Water hardness can impact the taste, quality, and effectiveness of soaps and detergents.
Hardness texture and color are examples of?
Color, texture, and hardness are examples of physical properties. Shape and size are two more examples.
What are the two natural elements found in water?
The two natural elements found in water are hydrogen and oxygen.
How do you control the hardness or softness of the water in the aquarium?
There are two ways to help control water hardness: use a packaged water softener or use a mechanical water softening unit. Packaged water softeners are chemicals that help control water hardness.
What type of hardness?
Hardness is a breaking strength measurement of pellet as multiparticulate dosage form prepared with water (granulation liquid). This hardness is a very important in assessment or characterization of pellet, a good hardness is preferable for coating step of pellet.

Permanent hardness of water due to?
Permanent hardness of water is typically caused by the presence of calcium sulfate (CaSO4) and magnesium sulfate (MgSO4) in the water. These minerals do not precipitate out of solution when water is boiled, unlike temporary hardness caused by calcium bicarbonate which can be easily removed by boiling. Permanent hardness can be removed through processes like ion exchange or chemical precipitation.
What are two forms of water ii found in a rain forest?
Rain, fog and gaseous form, liquid pools.
What are two types of carbon?
Two types of carbon are graphite and diamond. Graphite is a soft, dark gray form of carbon, while diamond is a colorless, transparent form of carbon renowned for its hardness and brilliance.

What form is most of earths water in?
Only about 3% of Earth's water is fresh. Two percent of the Earth's water (about 66% of all fresh water) is in solid form, found in ice caps and glaciers. Because it is frozen and so far away, the fresh water in ice caps is not available for use by people or plants. That leaves about 1% of all the Earth's water in a form usable to humans and land animals. This fresh water is found in lakes, rivers, streams, ponds, and in the ground. (A small amount of water is found as vapor in the atmosphere.)
Can you Give me name of two pollutants found in air which make rain-water more acidic?
Two pollutants found in air that can make rain water more acidic are sulfur dioxide and nitrogen oxides. These pollutants can react with water in the atmosphere to form sulfuric acid and nitric acid, which then fall to the ground in the form of acid rain.
What is the difference between temp hard water and permanent hard water?
here two type of hardness 1-temporery 2-permanent *temporery hardness-it is also known as carbonate hardness and alkiliny hardness.it is unstable hardness.it is remove by boiling.it is the due presence of carbonate.

Why do they change swimming pool water every 8 years in California?
Water is changed when calcium hardness, cyanuric acid, or total dissolved solids become too high. In Las Vegas we recommend every two years due to high calcium hardness.
