Why come again colour change after endpoint of titration of sodium thiosulphate with iodine?
The color change occurs because iodine reacts with starch to form a blue-black complex. Initially, the iodine reacts with the sodium thiosulfate until it is completely consumed, resulting in a color change from yellow to brown. Once the sodium thiosulfate is depleted, any excess iodine present reacts with the starch indicator, causing the solution to turn blue-black, indicating the endpoint of the titration.
How does the sodium potassium pump operates?
The sodium-potassium pump functions much like a revolving door. Its main job is to keep sodium ions (NA+) outside of the cell and keep potassium ions (K+) inside of the cell. With the addition of energy from an ATP molecule, the sodium potassium pump moves three sodium ions out of the cell and moves two potassium ions into the cell with each turn. The goal of this process is to return, or keep, the cell at a resting state, or resting potential.
How do you check the presence of sodium in different in different compounds?
One common way to check for the presence of sodium in compounds is by using a flame test. When the compound is heated in a flame, sodium will produce a characteristic bright yellow color. Alternatively, sodium compounds can also be detected by performing chemical tests, such as using silver nitrate to precipitate sodium chloride.
What color does gold turn during a flame test?
Unfortunately the visible colors produced in gold flame are too weak to be useful. About tenth of sodium yellow, calcium red, or potassium violet flames, which also are clearer to the expert eyes.
Why does the test tube turn yellow in electrolysis water experiment?
The yellow color in the test tube during an electrolysis water experiment is typically due to the presence of bromine or iodine. These elements can be released during the electrolysis process when the electrodes are made of certain materials that react with the electrolyte solution, such as potassium bromide or potassium iodide.
Standardization of sodium thiosulphate by potassium iodate?
In this titration method, a solution of potassium iodate is used as the titrant to determine the concentration of sodium thiosulfate solution. It involves adding potassium iodate to sodium thiosulfate solution until the reaction is complete, as indicated by the disappearance of the starch-iodine complex's blue color. The reaction is: 5Na2S2O3 + 2KIO3 + 2H2SO4 -> 2Na2SO4 + K2SO4 + 5I2 + 5H2O.
When you burn sodium oxide what colour does it turn?
When sodium oxide is burned, it typically produces a yellow flame.
Can going from one potassium pill to two cause urine to turn yellow?
no it turns it pink

Why does sodium chloride turn salt pool water yellow?
sodium chloride is salt, it may be causing a reaction with other chemicals in the pool such as hydrogen peroxide and sodium hypochlorite (Bleach)

Does the solution of thiosulphate reaction turn cloudy?
Yes, the solution of thiosulfate reaction can turn cloudy due to the formation of sulfur or sulfur particles during the reaction. This cloudiness is a result of the precipitate that forms when thiosulfate reacts with certain substances.
What happens when you cut sodium or potassium?
When you cut the likes of sodium or potassium it leaves a shiny surface which will quickly turn dull as they react with Oxygen in the air. To prevent them reacting with any of the air, these elements are usually kept in oil.
How did the smurfs make the potian to make the moon turn blue?
50% blue food colouring. 25% potassium nitrate 17% calcium hydroxide 13% sodium valproate
