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.
How do you no if you have hard water?
The water wouldn't form lather(foam) with soap,it would waste soap. It could be cold because most hard water are cold. Solution is boiling,using detergents because it dissolv es than solid or bar soap.
What is the difference of soap solution and detergent solution in terms of their reaction with tap water?
introduction of soap solution introduction of soap solution
How do you we prepare cresol with soap solution?
cresol is prepared with soap solution as it is more soluble in the soap solution than water . moreover soap solution enhances its detergent and disinfectant properties.
What S forms when soap is used in hard water?
Hard water does not produce lather. So soap does not work effectively with hard water as soap does not form a good lather with hard water.
Is mixing liquid soap and water a solution?
Yes, it is a solution.
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.
How do you prepare soap solution for testing hardness of water?
titrate water with standard soap solution .End point is when floating bubbles aee stable
Dissolve hard-water buildup on plastic?
To dissolve hard water buildup on plastic, the plastic can be sprayed with a solution of white vinegar and water. Let the solution stay on the material for a while, then wash with a dish soap and rinse well. Smaller pieces can be soaked in vinegar and water for a while, then washed.
What is the solvent in soap solution?
When soap is added to water, water is the solvent
Explain why soaps can be effective in hard water if relatively large quantities of soap are added to water?
A soap is an organic molecule that has a polar/hydrophilic end and a nonpolar/hydrophobic end. The polar end typically has a hydroxyl functional group, which acts like a weak acid in water. Hard water is water that has a relatively large solute load, typically calcium, magnesium and other metals. When you add a soap to hard water, the metal ions in the water attach themselves to the polar end and you get a precipitate of the salt form of the soap. This inactivates the soap. However, if you add enough soap, you will effectively "soften" the water by pulling enough metal ions out of solution to still have active soap molecules in the water.
What is meant by hard water?
water that has run over chalk and still has these types of particles in. When mixed with soap solution forms a scum. However, soft water when mixed with soap solution forms a precipitate. ------ Water containing some soluble hydrocarbonates of calcium and magnesium as Ca(HCO3)2 and Mg(HCO3)2 - temporary hard water or Water containing another salts of calcium and magnesium (as chlorides, sulfates, nitates) - permanent hard water Total hardness is the sum of temporary and permanent.
