Is soap water soluble or insoluble?
Soluble
How do you test insoluble matter in soap?
To test for insoluble matter in soap, you can perform a simple solubility test by dissolving a small amount of the soap in water and observing if any residue remains. If there is residue, filter it out and dry it to determine the amount of insoluble matter present in the soap. The percentage of insoluble matter can then be calculated by dividing the weight of the residue by the initial weight of the soap sample and expressing it as a percentage.
What principle is involved in the determination of the volume of an irregularly shaped water insoluble solid?
This is the Archimedes principle.
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.
If tap water and soap form an insoluble deposit is this a physical or chemical change?
The formation of an insoluble deposit when tap water and soap are mixed is a physical change, not a chemical change. In this case, the molecules of the soap and tap water are simply rearranging themselves to form the deposit, without any new substances being formed.

Metal ions in water can react with soap to form what?
Metal ions in water can react with soap to form insoluble salts, known as soap scum. This can lead to reduced soap efficacy and result in soap scum buildup on surfaces.
Why is matter insoluble in alcohol determined in soap and detergents?
Matter can be insoluble in alcohol in soap and detergents because alcohol is hydrophilic (water-loving), while some components in soap and detergents are hydrophobic (water-repelling). This difference in polarity between the alcohol and the matter prevents them from mixing and dissolving in each other.
What is the name of the compounds that are responsible for the formation of white insoluble scum?
The compounds responsible for the formation of white insoluble scum are typically calcium and magnesium salts of fatty acids, known as soap scum. These salts can accumulate on surfaces in contact with soap and hard water, leading to the formation of the white residue.

How washing of cloth with the soap clean the cloth?
Detergents such as soap solubilize the water-insoluble hydrophobic substances from the cloth while water solubilizes the water-soluble substances. Once the substances are solubilized, they can be washed away.
Why do soaps not work in hard water?
Soaps do not work well in hard water because the minerals in hard water, such as calcium and magnesium, react with the soap molecules to form insoluble compounds called soap scum. This reduces the effectiveness of the soap for cleaning and can leave a residue on surfaces.
What happens when calcium chloride is added to a soap that lathered most?
When calcium chloride is added to a soap that lathered well, it can form insoluble calcium salts with the fatty acids in the soap. This can reduce the effectiveness of the soap by decreasing its ability to form lather and clean effectively.
