Yes, surface tension can change when bleach is added to water. Bleach is a surfactant that can reduce the surface tension of water by disrupting the hydrogen bonding between water molecules. This can lead to a decrease in surface tension and cause water to spread more easily.

Which describes surface tension of water when detergent is added A increases B decreases C becomes zero D shows no change?

B) Decreases. When detergent is added to water, it reduces the surface tension by disrupting the hydrogen bonding between water molecules. This causes the water molecules to spread out more evenly across the surface, lowering the surface tension.


Why the change in surface tension is much less when sodium chloride is added to water in place of an equivalent amount of ethanol?

Sodium chloride is an ionic compound that dissociates into ions when dissolved in water, causing no significant change in the cohesive forces between water molecules. Ethanol, on the other hand, is a covalent compound that disrupts the hydrogen bonding between water molecules, leading to a greater change in surface tension.


True or false Addition of a detergent to water increases the surface tension of the water?

False. Addition of a detergent to water decreases the surface tension of the water by disrupting the hydrogen bonding between water molecules, allowing it to spread out more easily and interact with other substances.


Can a needle float in soapy water?

Yes it is not possible. Because as soap is added then surface tension would get reduced and so possibility of float becomes less. When we carefully place the same needle on ordinary water floating is quite possible as water has more surface tension


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 are surfactants?

A substance that tends to reduce the surface tension of a liquid in which it is dissolved.

Why is it that a needle may float on a clean water but sink when detergent is added to the water?

When a needle is placed on clean water, it can float due to surface tension, which is the cohesive force between water molecules at the surface. However, when detergent is added to the water, it reduces the surface tension by disrupting the cohesive forces between water molecules. This decrease in surface tension causes the needle to sink as the water can no longer support its weight.


What were the properties of water that allowed pennies to continue to be added to the glass of water?

The properties of water that allowed pennies to continue to be added to the glass are surface tension and cohesion. Surface tension creates a "skin" on the surface of the water, allowing the pennies to sit on top without sinking. Cohesion is the ability of water molecules to stick together, helping to support the weight of the pennies as they are added.


Is Surface tension of water affected by potassium permanganate?

Potassium permanganate can potentially alter the surface tension of water, as it is a strong oxidizing agent. When added to water, it can break down organic compounds and reduce the surface tension. However, the effect may vary depending on the concentration of potassium permanganate and other factors.


What happens when detergent is added to the floating object in the water?

When detergent is added to a floating object in water, it can break the surface tension of the water causing the object to sink. This happens because the detergent molecules disrupt the cohesive forces that keep the object floating by reducing the surface tension of the water.


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.


Why does oil in a bowl of water get repelled when washing liquid is dropped on it?

The oil is not repelled. It is floating on the surface of the water as a thin film. Water has very high surface tension, but when soap or detergent is added to water that surface tension suddenly drops. The water surface now contracts like a punctured rubber sheet toward the remaining area of high surface tension, dragging the oil film floating on its surface with it.

False. Addition of a detergent to water decreases the surface tension of the water by disrupting the hydrogen bonding between water molecules, allowing it to spread out more easily and interact with other substances.


Why does the pepper run away when soap is added?

Soap disrupts the surface tension of water. So if you have fine particles floating in water (I personally use parsley flakes, which float better than pepper does) and you put a tiny trace of soap on your finger, and then touch the water, it breaks the surface tension at that point - but the surface tension of the water on the OTHER side of the flake is unchanged. The surface tension pulls the flakes away from the soap. So the flakes aren't running away - they are being released from the surface tension!


What does baby powder do to water's surface tension?

Baby powder reduces the surface tension of water. When added to water, baby powder disrupts the hydrogen bonds between water molecules, reducing the cohesive forces on the surface of the water and causing it to spread out more easily.
