detergents have a hydrocarbon chain like C12H25 which is nonpolar, and an ionic group like sulfate. What happens here is that your hydrocarbon end is attracted by dirt, oil and greasy stuff, and that ionic end is attracted by the water.
SOOO... your result is that an orientation of molecules uhhh
at the interface between dirt and water where the dirt particles get suspended as a colloid, so then they easily get washed away.
Now that being said if you add detergent or salt to water is the same as adding a solute to a solution which lowers the vapor pressur of a liquid. SOOO... a higher temp is needed to increase the vapor pressur of the solution to get it to the gas phase.
So here the soap is the emulsifyer and the negative ions are oriented between oil and water and the positive ions move independently through the water. Becuz they do this temporary dipoles called London forces are produced between the positive part of the ions and the negative part of the hydrogen bond, on the oxygen.
When salt is added to water, it dissolves due to the attraction between the positive and negative ions in the salt and the water molecules. This creates a solution where the salt molecules are dispersed throughout the water, forming a homogeneous mixture.
When salt is placed in a watch glass, it remains as solid crystals. If water is added, the salt will dissolve depending on the amount of water added. The solution may evaporate, leaving behind the salt crystals.
What did you observe! This is not a question we can answer as we were not present when the salt was added.
Salt added to water form a solution, an electrolyte.
You create a solution of the salt in water.
it rises slightly
It melts slowly.
Salt water has a higher density, so the pressure at a given depth increases.
U evaporate it
When salt is added to water, it dissolves due to the attraction between the positive and negative ions in the salt and the water molecules. This creates a solution where the salt molecules are dispersed throughout the water, forming a homogeneous mixture.
It just stays there. some is lost to the backwash , splashing, overflow and so on but the salt that is in the water stays there.
When iron powder and salt are added to water, the iron powder will react with the water to produce iron oxide (rust), hydrogen gas, and heat. The salt will dissolve in the water. This reaction is a chemical change, resulting in a mixture of iron oxide, hydrogen gas, salt solution, and any unreacted iron powder.
Salt decreases the freezing point of water, causing the ice to melt. This happens because the salt lowers the temperature at which the ice can exist in a solid state, leading to the ice absorbing heat from its surroundings and melting.
the salt dissolves and the water will become salt water
You get salt water.
If you add the salt to the water, the density of the water increases. so the what ever floats on the water will come up. That mean it will get immersed in the water to less extent. If the salt does not dissolve in the liquid, like rock oil, there will be no difference.
When magnesium oxide is added to water, it will react to form magnesium hydroxide, a salt solution, and release heat. This reaction is exothermic and the magnesium hydroxide formed will be a white solid that will dissolve in water to form the salt solution.
