Is soap water soluble or insoluble?
Soluble
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?
dg
How do you test insoluble matter in soap?
through the copper sulphate test, magnesium sulphate and calcium chloride test.
If tap water and soap form an insoluble deposit is this a physical or chemical change?
The formation of a precipitate is a chemical change.

How you can made calcium soap of fatty acids?
Soap scum is calcium soap of fatty acids. It is the result of soap in hard water-- the fatty acids in soap bond with the calcium ions in hard water and create an insoluble compound.

Why is it difficult to use soap in an acid solution?
Soap is a salt of carboxylic acid (fatty acid) in acidic medium soap forms the corresponding fatty acid which is almost insoluble in water so soap does not work properly.

If tap water and soap form an insoluble deposit is this a physical or chemical change?
The formation of a precipitate is a chemical change.
Why do we say that soap gets wasted if hard water is used for cleansing purpose?
Mineral ions from hard water (generally calcium and magnesium) react with soap forming insoluble and diasagreeable precipitates.
Why does NaCl heelp to precipitate the soap from aqueous soltion?
It depends on the salt. A salt of calcium, magnesium, or iron will form an insoluble compound that will precipitate with a soap molecule that is known as soap scum. Here is a typical reaction: Ca2+(aq) + 2C17H35COO-(aq) ==> (C17H35COO-)2Ca2+(s) Sodium chloride will not form a precipitate with soap as long as the soap is a carboxylate.
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.
What are the chracteristics of lead sulfide?
Lead sulfide is a black solution. It is insoluble in water and is a precipitate. The principle of the lead acetate test is the formation of lead sulfide.
