The needle floats on the tensioned surface of the water. When the detergent is added, the surface tension is broken and the needle sinks. Larva of mosquitoes hang from the surface to breath air. Pond-skaters can move across the surface, as can many aquatic insects. Detergent will also cause insects to sink.

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 would happen if you added cabbage juice indicator to dishwasher detergent?
If the pH of a detergent is usyally greater then 7 the juice of red cabbage become blue to green in this solution.
Why is it that a needle may float on a clean water but sink when detergent is added to the water?
When detergent is added to water, it reduces the surface tension of the water. This makes it easier for the needle to break through the water's surface and sink, as the cohesive forces that were holding the water molecules together are weakened. Without the detergent, the surface tension of the water is strong enough to support the needle and allow it to float.
Why was detergent added to the bicarbonate solution in leaf lab?
Detergent was added to the bicarbonate solution in the leaf lab to break down the cell membranes of the plant cells. This process releases the chlorophyll and other cellular contents, allowing the experiment to better observe the photosynthetic activity. Additionally, the detergent helps to increase the solubility of gases, facilitating the uptake of carbon dioxide for photosynthesis.
Does adding detergent to water make it more dilute or concentrated?
Adding detergent to water does not make it more dilute or concentrated. Detergent dissolves in water, so it is considered a solution. The concentration of the detergent in the water depends on the amount of detergent added.
What will happen when a crystal of solute is added to an unsaturated solution?
It will dissolve
When liquid is added to a solution of a detergent in water the detergent breaks up large globules of the lipid into much smaller globues what effect do you think a detergent would up large globules o?
Adding a detergent to a solution with large globules of lipids helps break them down into smaller globules due to the detergent's ability to lower surface tension. This allows the lipids to disperse more evenly in the solution, improving their solubility and making it easier to wash away dirt and grime from surfaces.
What happen when detergent is added to boiling water?
When detergent is added to boiling water, it can cause the water to foam up and create a lot of bubbles. This is because the detergent molecules decrease the surface tension of the water, causing bubbles to form more easily. However, adding detergent to boiling water shouldn't have any harmful effects and is commonly done during cooking or cleaning processes.
Why was detergent added to extraction buffer?
because it can break through the membranes to get to the DNA
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.
How can medications be administered intravenously?
minerals like potassium and calcium, vitamins, or drugs can be added to the IV solution by injecting them into the bottle or bag with a needle.
