Brown turbidity in the titration of KMnO4 with oxalic acid may be due to the formation of manganese dioxide (MnO2). This reaction occurs in acidic conditions and indicates that the end point of the titration has been reached. MnO2 is insoluble and can appear as a brown precipitate, causing turbidity in the solution.
Brown turbidity may be observed when titrating KMnO4 with oxalic acid due to the formation of manganese dioxide (MnO2) as a byproduct. This occurs when excess oxalic acid reduces MnO4- to Mn2+ ions, which then react with oxygen in the air to form manganese dioxide. The brown color of MnO2 leads to turbidity in the solution.
When carbon dioxide (CO2) is washed with potassium permanganate (KMnO4) water, the KMnO4 will be reduced by the CO2 to form a brown precipitate of manganese dioxide (MnO2). This reaction can be used to determine the presence of CO2 in a gas sample by observing the color change from purple (KMnO4) to brown (MnO2).
In the titration of KMnO4, no indicator is used because KMnO4 is a self-indicating titrant. It undergoes a color change from purple to colorless (or brown) at the endpoint of the titration, which makes it unnecessary to add an external indicator. The precise endpoint can be easily detected visually, making the use of an indicator redundant.
Bromine reacts with an alkane to produce a colorless solution, due to the formation of a colorless alkyl halide. On the other hand, potassium permanganate (KMnO4) reacts with an alkane to form a brown precipitate of manganese dioxide.
2-butanone will give a positive test with Tollen's reagent, forming a silver mirror, while 2-methylbutanal will not react with Tollen's reagent. 2-methylbutanal will oxidize with KMnO4, turning the purple solution into a brown precipitate of manganese dioxide, while 2-butanone will not react with KMnO4.

Turbidity is a measure of the cloudiness or haziness of a fluid caused by suspended particles that scatter light. It is typically measured in Nephelometric Turbidity Units (NTU) using a turbidimeter or similar instrument. Higher turbidity values indicate a greater concentration of suspended particles in the fluid.

Add KMnO4 (Potassium Permanganate) which is a purple solution. If it is added to an alkene or alkyne it will turn colourless and produces a brown precipitate.

KMnO4 is used in TLC (Thin Layer Chromatography) as a staining reagent for the detection of alkenes and alkynes. It reacts with the double or triple bonds in the compounds, forming a brown precipitate that allows for easy visualization of the separated compounds on the TLC plate.
When potassium permanganate (KMnO4) and sodium hydroxide (NaOH) are mixed together, manganese dioxide (MnO2) is formed along with water and sodium manganate (Na2MnO4). This reaction is often used in analytical chemistry for titrations and redox reactions.
Hexane and benzene do not react in the ignition test. Only acetylene does. Acetylene has a triple bond if equivalent amount of KMnO4 is used. The equation is HCCH + KMnO4 -> HC (OH) = CH(OH).
