Write the reactions of hard water with soap which leads to the formation of white insoluble scum?
When hard water reacts with soap, it forms an insoluble scum due to the reaction between the calcium and magnesium ions present in the water with the soap. The calcium and magnesium ions react with the soap molecules to form calcium and magnesium salts of the fatty acids, which are insoluble and appear as white scum in the water.
What can you find dissolved in large quantities in hard water?
Calcium and magnesium are typically found dissolved in large quantities in hard water. These minerals can cause a buildup of scale in pipes, appliances, and fixtures over time.
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).
Element y combined with element u can be found in 'hard water'?
The elements y and u in hard water usually refer to calcium (y) and magnesium (u) ions. These minerals are responsible for making water hard, which can lead to issues like scaling in pipes and reduced efficiency of soap.
Mineral that is higher concentrations in hard water than in soft water?
Calcium is a mineral found in higher concentrations in hard water than in soft water. The presence of calcium and magnesium carbonates and sulfates makes water hard, which can lead to mineral deposits in plumbing systems and appliances. Soft water typically contains lower levels of these minerals due to the filtration or removal of calcium and magnesium ions.
What can you find in large quantities in hard water?
Usually calcium & magnesium ions.
What are the two ions that are most commonly responsible for hard water?
Calcium ions (Ca^2+) and magnesium ions (Mg^2+) are the two ions most commonly responsible for hard water. These ions can form insoluble salts with soap, leading to reduced lathering and the formation of scum in hard water conditions.
Is hard water a mixture or compound?
Hard water is a mixture: water containing calcium and magnesium carbonates, also some sulfates or chlorides.
What ions are present in hard water if it contains calcium chloride dissolved in distilled water?
In hard water containing calcium chloride dissolved in distilled water, the ions present would be calcium (Ca2+) and chloride (Cl-). The calcium ions come from calcium chloride, while the chloride ions come from the dissociation of calcium chloride in water.
Element that is responsible for making water hard?
The metal cations are responsible for making water hard. Examples of these cations includes the calcium ions, the magnesium ions, the aluminum ions, and the manganese ions.
What pair of ions is present in hard water?
Large quantities of calcium and magnesium ions make water hard.

The calcium and magnesium ions react with the soap molecules to form calcium and magnesium salts of the fatty acids, which are insoluble and appear as white scum in the water.
Why river waters are generally rich in calcium and magnesium ions?
River waters can become rich in calcium and magnesium ions through the weathering of rocks and minerals such as limestone, which contain these ions. As river water flows over and interacts with these rocks, they dissolve and release calcium and magnesium ions into the water. These ions contribute to the hardness of the water.
What can you find dissolved in large quantities in hard water?
Calcium and magnesium are typically found dissolved in large quantities in hard water. These minerals can cause a buildup of scale in pipes, appliances, and fixtures over time.
Is calcium found in hard water?
YES, it's is the calcium that makes the water "hard". That is why you use a cleaner that has a calcium remover in it to get those hard water stains off.

What elements are found in 'hard water'?
Pure water is composed of two hydrogen molecules and one oxygen molecule, thus the formula H20. Outside of a lab, it is quite unlikely that you will encounter pure water. Dec. 17,2011 Water molecule consists of two hydrogen atoms and one oxygen atom. Hard water is not pure water. It contains ions such as calcium ions and magnesium ions. calcium ions cause permanent hardness whereas, magnesium ions cause temporary hardness. True, outside of a lab, natural water will always contain some chemical species, ions or undissolved microscopic materials that are not visible to the naked eye.
