I just got done talking with a vendor for pH probes and he explained that the KCl solution helps facilitate the measurement of the hydrogen ions with the electrode. It will actually seep out in small quantities from the tip which is a membrane.
as silver is less reactive than copper the silver when immersed will loose its electrons and the copper will displace it. i apologize if it is the wrong answer.... this is actually a guess :P
Sodium is kept immersed in kerosene because it reacts so vigorously that they catch fire when kept in the open. Hence to protect them and to prevent accidental fires, they are kept immersed in kerosene oil.
When exposed to air or moisture, sodium will catch fire and explode. So it is kept immersed in an inert or non-polar solvent (such as hexane, pentane) to prevent its contact with air or moisture.
Potassium ferrocynide is stored in dark coloured bottels and kept away from sunlight.This is because it decomposes when exposed to sunlight.Thus it is always stored in amber or brown coloured bottels.
Silver nitrate is kept in colored bottles to protect it from exposure to light. Light can catalyze the decomposition of silver nitrate, causing it to form colloidal silver which can reduce its effectiveness. Colored bottles help to block out light and preserve the stability of the silver nitrate solution.
Any reaction occur.
copper is placed above the silver in the ractivity series which indicates that copper is more reactive than silver . when a copper coin is kept immersed in a solution of siler nitrate ,silver from its solution will deposit on copper coin . copper slowly displaces silver from the silver nitrate solution and the colour of solution changes from colourless to blue due to the formation of copper nitrate . the copper coin will disappear and silver will percipate out .
Phosphorus is kept immersed in water to prevent its reaction with oxygen in the air, which can cause it to ignite spontaneously. Keeping phosphorus submerged in water helps to maintain its stability and prevent any potential hazards.

When a silver spoon is immersed in aqueous copper sulphate solution, a displacement reaction occurs. The silver spoon will react with the copper sulphate, displacing the copper ions and forming silver sulphate solution. Over time, the silver spoon will start to turn slightly reddish as a thin layer of copper is deposited on its surface.
Sodium is a metal that is commonly kept immersed in kerosene for storing because it reacts violently with water and oxygen in the air. Placing it in kerosene helps prevent these reactions and keeps the metal stable.
Sodium is kept immersed in kerosene because it reacts so vigorously that they catch fire when kept in the open. Hence to protect them and to prevent accidental fires, they are kept immersed in kerosene oil.
The object would behave as a part of fluid and it will remain where it is kept.
While I was in Portugal everyone kept a bowl on the table. As long as they are immersed in oil they keep.
Mitochondria are kept in sucrose solution to maintain their osmotic balance and prevent them from swelling or shrinking due to changes in their external environment. The sucrose solution helps to stabilize the mitochondria and maintain their structural integrity during the extraction process.
Sodium reacts violently with water, releasing hydrogen gas and forming sodium hydroxide. When sodium is kept immersed in kerosene oil, it is isolated from water, preventing the reaction from occurring. Kerosene oil acts as a barrier to keep oxygen away from the sodium, further preventing combustion.
He always kept Christmas
