What happen if the potassium permanganate solution drop to the water?
If potassium permanganate solution is dropped into water, it will dissolve and create a purple or pink solution. Potassium permanganate is a strong oxidizing agent and can be used for various applications such as disinfection and water treatment.
If you cool the solution slowly and sugar does not settle out as it cools you know the solution is?
Supersaturated
Does zinc displace hydrogen from cold water?
Zinc does not displace hydrogen from cold water, as zinc is lower in the reactivity series than hydrogen. However, if zinc is reacted with an acid, such as hydrochloric acid, it will displace hydrogen gas.
When edta is insoluble in distilled water then how to make 0.01N edta solution?
use heat to heat the solution and add EDTA slowly to dissolve it.
What happens when saturated solution at a certain temperature is cooled slowly?
As the saturated solution is cooled slowly, the solubility of the solute decreases due to the decrease in temperature. This causes the excess solute to start crystallizing out of the solution in the form of solid crystals. The crystals will continue to grow as more solute particles come out of solution until equilibrium is reached.
Why is the permanganate solution added slowly to hydrogen peroxide solution?
To avoid a violent reaction.
Why is the permanganate solution added slowly to the hydrogen peroxide solution?
To avoid a violent reaction.
Is hydrogen peroxide a heterogeneous or homogeneous mixture?
Hydrogen Peroxide (H2O2) is a compound, and liquid at room temperature. It is NOT a mixture. However, at room temeprature it slowly decomposes to oxygen and water. 2H2O2 = 2H2O + O2 It the oxygen remains in solution in water then it is heterogeneous solution, NOT Mixture.

What is the charge of hydrogen peroxide?
As H2O2 it is uncharged , but rather unstable., and will slowly decompose to water and oxygen.
Why does hydrogen peroxide evaporates slower than alcohol?
Hydrogen peroxide has stronger intermolecular forces (hydrogen bonding) compared to alcohol, leading to stronger attractions between its molecules that require more energy to break apart and evaporate. This results in hydrogen peroxide evaporating more slowly than alcohol. Additionally, hydrogen peroxide has a higher molecular weight compared to most alcohols, contributing to its slower evaporation rate.
Can an apple break down hydrogen peroxide?
Yes it can. I did it in science class just today, and it works. It happens slowly but it does break down hydrogen peroxide.
Can any type of yeast be used for elephant toothpaste?
Hydrogen peroxide (H2O2) is always decomposing to release oxygen and water, but it does so slowly. In elephant toothpaste, the hydrogen peroxide is mixed with detergent and food color and then saturated iodide solution is added. The iodide acts as a catalyst so that the H2O2 breaks down really quickly. All the gas bubbles released makes the detergent bubble up suddenly.
What happens when oxygen is prepared from hydrogen peroxide without adding a catalyst?
Hydrogen peroxide purchased from a store or science supply house has been stabilized so that expected loss due to spontaneous decomposition into oxygen and water is less than 3% per year. Without adding a catalyst, you will have to wait a very long time to collect the oxygen from a sample of hydrogen peroxide.
Why should H Ac be added slowly to the milk with through stirring?
Adding hydrogen peroxide slowly and with stirring helps to ensure uniform distribution within the milk, which is important for achieving the desired antimicrobial effect. Slow addition also helps prevent localized high concentrations of hydrogen peroxide which could have negative effects on the milk's composition or quality.
What safety precautions should be taken when handling a mixture of hydrogen peroxide and sulfuric acid?
When handling a mixture of hydrogen peroxide and sulfuric acid, it is important to wear appropriate personal protective equipment such as gloves, goggles, and a lab coat. Work in a well-ventilated area to avoid inhaling any fumes. Keep the mixture away from heat sources and open flames as it can be reactive and potentially hazardous. Additionally, always add the hydrogen peroxide to the sulfuric acid slowly and carefully to prevent splashing or spattering.
Why color of potassium permanganate disappear slowly first but quite fast afterwards in titration?
The color of potassium permanganate disappears slowly at first because it is being consumed by the reaction with the analyte in small increments. Once most of the analyte has reacted, the color disappears faster because there are fewer molecules left to react with. This leads to a more rapid consumption of the remaining permanganate ions.
