What happen when ethanol is heated with alkaline kmno4 solution?
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.
What chemicals can form brominea kmno4 b kbr or c h2so4 and d naoh?
a) KMnO4 is potassium permanganate, an inorganic compound used as an oxidizing agent. b) KBr is potassium bromide, a salt used in photographic chemicals and as a sedative in medicine. c) H2SO4 is sulfuric acid, a strong mineral acid used in various industrial processes. d) NaOH is sodium hydroxide, a strong base used in manufacturing paper, textiles, and cleaning products.
When KMnO4 and NaOH are mixed together what is formed?
Na2SO3 + KMnO4 ---> K2SO3 + NaMnO4 All solutions are aqeous. It's a simple double replacement reaction. Its a Redox Equation not a double replacement KMnO4 is a common oxidizing agent im not sure about the answer but i guess it has to change KMnO4 into MnO
What is the molArity of a hydrochloric acid solution 30.0mL of which is just neutralized by 48.0mL of 0.100M NaOH?
The reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) is 1:1, so the moles of NaOH used in the reaction can be used to determine the moles of HCl in the solution. Using the volume and concentration of NaOH, you can calculate the moles of NaOH used. Then, using the balanced equation, you can determine the moles of HCl, which can be used to find the molarity of HCl in the solution.
What is the product of oxidation of a mercaptan with a mild oxidant oxygen?
Mercaptan first extracted from the Gasoline/LPG by using caustic oxide which gives NaSR .it is further oxidised to regenerate the used caustic and mercaptan finally removed as Di-sulphides (extraction) RSH + NaOH NaSR + H2O (oxidation) NaSR + ¼O2 + ½H2O NaOH + RSSR regards VIJAYKUMAR
Why kmno4 is used to detect the amount of h202 used?
The color change with oxidation of the permangante changes from purple to clear allows the titration to be conducted without using a seperate indicator.

What is the formula for potassium permaangante?
KMnO4, used in a number of titrations as an oxidizing agent, also useful in organic reactions for the same purpose (usually oxidation of alkenes and alkynes).

How much of NaOH were used in the titration?
The amount of NaOH used in a titration depends on the volume and concentration of the NaOH solution used in the experiment. To calculate the exact amount of NaOH used, you would need to know the molarity of the NaOH solution and the volume used in the titration.
Why HCL is not use to acidify KMnO4 soln in permanganometric titration?
HCl cannot be used to acidify KMnO4 solution in permanganometric titration because it will react with KMnO4 reducing it to MnO2, which interferes with the titration process and affects the accuracy of the results. Instead, dilute sulfuric acid (H2SO4) is typically used to acidify the KMnO4 solution, as it does not interfere with the redox reaction between KMnO4 and the analyte.
How many moles of NaOH were used in the titration process?
The number of moles of NaOH used in the titration process can be calculated by dividing the volume of NaOH solution used by the molarity of the NaOH solution.
Is KMnO4 a base?
No, KMnO4 is not a base. It is a strong oxidizing agent commonly used in redox reactions to oxidize other substances.
Redox titrations of ferrous ion with KMnO4 why the HCl is not used in this reaction?
HCl is not used in redox titrations of ferrous ion with KMnO4 because it can react with KMnO4 and interfere with the titration process. HCl can reduce KMnO4, which would lead to inaccurate results by altering the equivalence point of the titration. Instead, a buffer solution is often used to maintain a constant pH during the titration.
