How might you ditinguish between hydrogyn peroxide and water?
One way to distinguish between hydrogen peroxide and water is to perform a chemical test with a catalyst, such as potassium permanganate. Hydrogen peroxide will react with the catalyst and produce oxygen gas, causing effervescence. Another method is to use a testing strip designed specifically to detect hydrogen peroxide, which will change color in the presence of hydrogen peroxide but not in water.
When do you use hydrogen peroxide in hair care?
Peroxide is bleach, you use it to strip hair of it's natural colour . Blonde and black hair go White after using
What chemical reaction occurs when you mix silver nitrate and a copper strip?
When you mix silver nitrate with a copper strip, a displacement reaction occurs. The more reactive copper displaces silver from the silver nitrate solution, forming solid silver and copper(II) nitrate solution. This reaction is represented by the equation: Cu(s) + 2AgNO3(aq) → 2Ag(s) + Cu(NO3)2(aq).
How does hydrogen peroxide affect human hair?
Hydrogen peroxide goes through the cuticle (colourless outside layer of the hair) and into the cortex (inside of the hair, has colour) and causes a reaction like an explosion and the colour breaks down and comes out of the hair.
How does Clinistix paper work?
A clinistrip is a urine test strip to measure levels of glucose in urine for diabetics. The small plastic strip has glucose oxidase and an organic dye on one end. The enzyme oxidizes glucose to gluconic acid with the formation of hydrogen peroxide. The hydrogen peroxide reacts with dye to produce a blue color. Each color corresponds to a specific level of glucose.
What materials did you use to create a battery in Lab 2?
blotter paper strip, zinc strip, copper strip, copper sulfate solution
What materials did we use to create a battery in Lab 2?
blotter paper strip, zinc strip, copper strip , copper sulfate solution
Why copper wire is appropriate choice to secure magnesium strip?
Copper wire is a good choice to secure a magnesium strip because copper does not react with magnesium, so it will not interfere with the chemical properties of the magnesium strip. Additionally, copper is malleable and ductile, making it easy to wrap around and secure the magnesium strip in place.
What happens when strip of zinc is dipped in copper sulphate solution?
When a strip of zinc is dipped in copper sulfate solution, a single displacement reaction occurs. Zinc, being more reactive than copper, displaces copper from the copper sulfate solution, forming zinc sulfate and depositing elemental copper on the strip. The solution changes color from blue (due to the copper sulfate) to colorless as zinc sulfate forms, and copper can be seen as a reddish-brown precipitate on the zinc strip.
Is copper strip malleable?
yes
Why the copper use in bimetallic strip thermometer?
Copper is used in a bimetallic strip thermometer because it is a good conductor of heat, allowing for accurate temperature readings. When the bimetallic strip is heated, the two metals with different thermal expansion coefficients cause the strip to bend, and copper's ductility helps maintain the strip's shape over multiple temperature cycles.
Is this 1995 pennies missing is copper worth anything?
Unlikely. A chemical reaction can strip off the thin copper coating and leave the silver-colored zinc behind, this is not a mint error and as such has no collector demand. Its worth only a penny.
