Are Nitrate compounds are insoluble and form precipitates?
No, nitrate compounds are typically soluble in water and do not form precipitates. Nitrate salts are highly soluble due to the strong attractive forces between the nitrate ion and water molecules.
How is soap scum formed?
In water that contains a lot of calcium ions (Ca^(2+)), these ion combine with the stearate/palmate anion of soap, to form calcium palmate or calcium stearate (scum). NB Water that contains a lot of calcium ions is often known as 'hard water'. because it is difficult for soap to lather.
What negative ion turns lime water milky?
The negative ion that turns lime water milky is the carbonate ion (CO3^2-). When carbon dioxide (CO2) is dissolved in water, it forms carbonic acid, which reacts with calcium hydroxide (lime water) to produce calcium carbonate (CaCO3). This calcium carbonate is insoluble in water and precipitates out, giving the solution a milky appearance.
How can Hard water convert into soft water?
Hard water refers to water that has very high mineral content, which affects its behavior in pipes and its affect on other chemicals like soap, where it often causes the formation of soap scum. Hard water also has a tendency to form deposits in pipes. Normally you wouldn't WANT to make water become hard, and there are systems for trying to reduce the "hardness" of water in the pipes of your home.
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.
Does the hardness of water depend upon the metal or non metal ion of the mineral?
The hardness of water depends primarily on the concentration and chemical identities of the metal cations dissolved in the water. The non metal ions dissolved in the water have little effect unless the particular ions are capable of forming coordinate covalent bonds to the metal ions.
Is hard water a solution?
Hard water is just a term. Various salts and minerals are dissolved (are solutes) in hard water. These may include Calcium, Iron, Chloride Ion, Sodium, and Potassium.
What is the advantage of a qual scheme that not only identifies but simultaneously precipitates a particular ion?
Why the hell can't these questions ever be answered?....
How does the amount of water softener needed to soften hard water depends upon the calcium ion concentration?
The relation is proportional.
Is calcium stearate a soap or a salt?
Soaps are usually salts of long chain fatty acids with Sodium or Potassium ion and are soluble in water but Calcium stearate is very slightly soluble in water so can not be used as soap so it is better to consider it as a salt only.
What is cleansing action of soap?
Because soap is a salt, it partially separates into its component ions in water. The active ion of the soap molecule is the RCOO-. The two ends of this ion behave in different fashions. The carboxylate end (-COO-) is hydrophilic (water-loving), and is said to be the "head" of the ion. The hydrocarbon portion is lipophilic (oil-loving) and is called the "tail" of the molecule. This unusual molecular structure is responsible for the unique surface and solubility characteristics of soaps and other surfactants (agents affecting the surface of a material). In a mixture of soap and water, soap molecules are uniformly dispersed. This system is not a true solution , however, because the hydrocarbon portions of the soap's ions are attracted to each other and form spherical aggregates known as micelles. The molecules tails that are incompatible with water are in the interior of these micelles, while the hydrophilic heads remain on the outside to interact with water. When oil is added to this system, it is taken into these micelles as tiny particles. Then it can be rinsed away.
Is calcium stearate considered a soap or a salt?
Soaps are usually salts of long chain fatty acids with Sodium or Potassium ion and are soluble in water but Calcium stearate is very slightly soluble in water so can not be used as soap so it is better to consider it as a salt only.
