What happens when potassium permanganate is standardized with ethanedioic acid?
When potassium permaganate is mixed with ethanedioc acid the potassium permanganate Mn04- ion will be converted toMn2+, this means that you will observe the purple colour changing to a clear solution and the permanganate ion is oxidised. The Mn2+ will act as an auto catalyst speeding up the reaction, therefore a funny rate will occur, where the reaction is slow to start, before speeding up and slowing down again at the end. I read about this in chemistry review, so you can check it out there...http://www.york.ac.uk/depts/chem/chemrev/autocat.doc.
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
What is meant by internal indicator?
Sometimes one of the reactants in a titration act as an indicator; this is an internal indicator. An example is the volumetric technique of permanganometry.
What is a natural pigment that can act as an indicator?
Anthocyanin is a natural pigment found in many fruits and vegetables such as red cabbage, berries, and grapes. It can act as a pH indicator, changing color in response to changes in acidity or alkalinity.
Which test is the best indicator of how well you do on the act?
Aspire.
What are the properties of KMnO2?
Potassium permanganate (KMnO4) is a dark purple, crystalline solid that is highly soluble in water, producing a deep purple solution. It is a strong oxidizing agent, often used in redox reactions, and has antimicrobial properties, making it useful in water treatment and disinfection. KMnO4 is also known for its ability to act as a reagent in organic chemistry. Additionally, it can decompose when heated, releasing oxygen and resulting in potassium manganate.
Is acesulfame potassium safe for dogs?
Acesulfame potassium does not act like xylitol in dogs. Xylitol is extremely toxic, acesulfame potassium is apparently not.
What is a natural pigment that can act a s an indicator called?
strawberry
How do you act when lots of girls like you?
Act your self! :)
What base is methyl indicator?
Methyl indicator is typically found in its protonated form, which means it has the potential to act as a weak base when it accepts a proton.
Is potassium acetate a weak acid?
No, potassium acetate is a salt formed by the reaction of a strong base (potassium hydroxide) with a weak acid (acetic acid). Potassium acetate is neutral and does not act as an acid in aqueous solutions.
Why table reagent sulfuric acid is used in oxalic acid before titration with potassium permaganate?
If the temperature is too low (below 55 degrees celsius), the interaction between the oxalate and the potassium permangante will move too slow as to be used as a practical lab experiment. *** Above 60 degrees celsius, oxalate acid begins to decompose, so its important to stay in this range If the temperature is too low (below 55 degrees celsius), the interaction between the oxalate and the potassium permangante will move too slow as to be used as a practical lab experiment. *** Above 60 degrees celsius, oxalate acid begins to decompose, so its important to stay in this range
