the hardness of water is mainly due to the presence of Ca or Mg ions.when hard water containing these ions is treated with soap solution it reacts to form white curdy ppt. known as "scum".
2C17H35COONa + Ca+2 -------> (C17H35COO)2Ca + 2Na+
(soap soln) (scum)
the hardness is divided into two:
1) permananent Hardness(because of the precense of salts of ca or mg ions)
2) Temporary Hardness(due to the precense of bicarbonates)

How to clean plastic window blinds?
Just take a damp rag and wipe it off. If it's something hard, like dried food, take them down(If you can), and use a scrubby. Lay it on a hard surface, and scrub hard. Eventually, it should come off.If you can take them off, put them in the bath and soak in a solution of warm water and dish washer detergent.
What causes hard water?
Dissolved minerals in the water. In most cases it is better to water your garden with hard water instead of treated water. The plants typically like the minerals found in hard water.
Is tap water healthy for you?
yes! you can get different types of water that come out of taps. you can get hard water and you can get soft water. hard water has relatively large amounts of calcium and magnesium salts dissolved in it. this is because water is a good solvent. as rain falls from clouds, some of the carbon dioxide dissolves in the water to form carbonic acid (this is very dilute and is not harmful). as the carbonic acid moves through different calcium and magnesium minerals to form hard water. this is proven to help reduce the risks of heart disease. also, some people say it tastes better too ;). a disadvantage though is that it can cost a little more money to have because you need more soap for it to lather and produce bubbles. also it produces lime scale. you can transform hard water into soft water by removing calcium and magnesium ions. this cam be achieved by adding washing soda (sodium carbonate) or by passing it through an ionic exchange column. lol soft water is the opposite and is just plane H2O.
What problems does hard water cause?
What problems does hard water cause? If you wash clothes with hard water they will often look scratchy or feel very harsh. Often if you bathe with soap and hard water you will have a sticky film of soap left on you. If you wash dishes mainly in a dishwasher with hard water you will have spotting or a film on your dishes or cooking utensils. Some things that are convenient about hard water is that it works just fine for watering your garden, washing or rinsing you driveway, and it is fine for most outdoor lawn care things.
What water produces more lather when soap is added?
Soft water produces more lather when soap is added compared to hard water. Soft water has fewer minerals, such as calcium and magnesium, which can react with soap to form a scum that reduces lather production.
Do you need more laundry detergent in soft water than in hard water?
No, you typically need less laundry detergent in soft water compared to hard water. Soft water allows the detergent to lather more easily and be more effective, whereas hard water may require higher amounts of detergent to achieve the same level of cleanliness.
Why does detergent lather in hard water easily?
Detergent lathers more easily in hard water because the minerals in hard water like calcium and magnesium ions react with soap molecules to form insoluble salts, preventing the soap from sudsing up effectively. In contrast, synthetic detergents are specifically designed to work better in hard water by not forming these insoluble salts, resulting in more lather.
How does hard water affect a detergent?
Hard water contains minerals like calcium and magnesium that can react with detergents, forming insoluble salts that reduce the detergent's effectiveness. This can result in reduced lather formation, poor cleaning performance, and residue build-up on clothes and dishes. Additionally, more detergent may be required to overcome the effects of hard water.
What is the effect of soap and detergent in the hard water?
One effect of soap and detergent in hard water is it will not lather as well as it does in soft water. This can affect the way the soap or detergent cleans in hard water making them less effective.
Which water does not form enough lather with soap?
hard water
Why doesn't soap and detergent have the same effect on different types of water?
Water hardness plays a significant role in how soap and detergent behave. Hard water contains minerals that can react with soap to form scum, reducing its cleaning effectiveness. Detergents, on the other hand, are designed to be more effective in hard water by using synthetic surfactants that do not react with minerals.
Which water do you get the most lather?
Hard water tends to produce less lather compared to soft water. This is because hard water contains minerals like calcium and magnesium which can react with soap, forming insoluble compounds that reduce lather formation. Soft water, on the other hand, does not contain these minerals and allows soap to lather more easily.
How do you do soft water from hard water?
Water is a universal solvent and there are two types of water i.e hard water and soft water. Soft water is the water that easily lather with soap while hard water does not lather with soap and is also of two type i.e temporary and permanent.
What effect does hard water have on a detergent?
potaSome laundry detergents do not produce as many suds in hard water, these are likely to be soap-based products and do not work as well in hard-water as detergent based products.Hard water affects the chemistry of the action between detergents and water to prevent it from forming a good lather. This can affect the cleaning power of the detergent and reduce its effectiveness.Nowadays, there are washing powders and liquids available for a wide range of water hardness. Make sure you choose the correct detergent for your area; you may also need to use slightly more detergent than the manufacturers recommended amount to compensate for the hard water. In many cases the manufacturer will give specific instructions on how to use the product in hard water areas, look out for these labels on your product.
How hard is your water and what impact does it have on your daily activities?
The hardness of water refers to the amount of minerals it contains, like calcium and magnesium. Hard water can make it harder to lather soap, leave spots on dishes, and cause buildup in pipes and appliances. It may require more soap or detergent to clean effectively.
Why synthetic detergent is more effective cleanser in hard water?
synthetic detergent contain hydrophobic and hydrophilic substance.the head(hydrophilic) contain sodium zedite.it can react with the ion in hard water and will become more effective.they can contact together. example of hard water is sea water,it contain ion such as calcium and magnesium.these ions will react with sodium zedite and make synthetic detergent is more effective cleanser in hard water.
