True or false Addition of a detergent to water increases the surface tension of the water?
False. When detergent or soap is added to water then it surface tension decreases.
Surface tension of water on adding detergent to it?
Decrease
What effect does detergent have on surface tension and Why?
There is an effect on Surface Tension when detergent is put in the water. I am doing an experiment for my upcoming Science fair and i am doing a Detergent Powered Boat/Surface Tension...I have tested it many times with and without detergent, when it doesn't have detergent it floats and then sinks after 5 seconds but with detergent it zips through the water...I can not give you the reason for this as i am myself still researching on why this is!
Surface tension of water on adding detergent?
Well If you have a pie pan filled with milk and then drop 4 diffrent colors of food coloring droped in but not touching then get a tooth pick with detergent on it and touch it in the foodcoloring will swirl out like tie die in the pan.
What is the effect of detergent on the surface tension of milk?
since milk has water as a main component, water has surface tension as the forces adhesion( sticks to stuff like the side of the glass) are stronger that the cohesion (makes water keep to itself) forces
What causes detergent to lower the surface tension of water?
Some mood music.
How can you break the attachment of molecules in the surface tension?
The surface tension of water can be broken by adding dishwashing detergent to the water. This can be demonstrated by filling a bowl with water, then floating a needle in it. This may sound almost impossible, but it can be easily achieved by placing the needle on a tissue, then carefully floating it on the water. When the tissue sinks, the needle should remain on the surface. It is prevented from sinking by the water's surface tension. Carefully add one drop of dishwashing detergent, and the needle will sink. You can prove this was due to the surface tension being broken by trying to float the needle again. If you added enough detergent this should be impossible, as detergent acts as a wetting agent and breaks the surface tension.
Why is it that a needle may float on a clean water but sink when detergent is added to the water?
Because the detergent reduces the surface tension of the water.
What is the effect of detergent on the surface tension?
Detergent has the effect of reducing the size of the water molecules thereby reducing the surface tension of the water. This allows for the small water molecules to integrate themselves farther into fabric to remove contaminants.
What will happen to a needle if pinch of detergent is added to a water?
If you have floated a needle on the surface of the water in a glass then adding a little detergent will cause the needle to sink. This is because the presence of the detergent changes the surface tension of the water so that it can no longer support the needle.
What happened to the needle when you added 2-3 drops of the detergent solution?
If you have floated a needle on the surface of the water in a glass then adding a little detergent will cause the needle to sink. This is because the presence of the detergent changes the surface tension of the water so that it can no longer support the needle.
What are the main ingredients of laundry detergent?
A main ingredient of laundry detergent is Surfactant. This substance when added to water reduces the surface tension of the water; which in turn enables the water to wash things better.
