When the free ends of tester are dipped into a solution the magnetic needle shows deflection can you explain why?
The solution likely contains ions that conduct electricity, creating a closed circuit with the tester. When current flows through the tester, it generates a magnetic field that interacts with the magnetic needle, causing it to deflect. This phenomenon is known as magnetic induction.
What else can I help you with?
When the free ends of a tester are dipped into a solution the magnetic needle of a compass shows deflection. Can you explain the reason?
The deflection of the magnetic needle in the compass is due to the flow of electric current when the free ends of the tester, such as a galvanometer, are dipped into the solution. The electric current creates a magnetic field around the tester, which interacts with the Earth's magnetic field, causing the needle in the compass to show deflection.
What wave property can best explain the apparent bending of pencil when its dipped in a glass of water?
Refraction of light can best explain the apparent bending of a pencil when it is dipped in a glass of water. This is due to the change in speed of light as it passes from air into water, causing the light rays to bend.
What wave property ca best explain the apparent bending of a pencil when it is dipped into a glass of water?
Refraction can best explain the apparent bending of a pencil when it is dipped into a glass of water. Refraction is the bending of light waves as they pass from one medium to another with a different density, such as air to water, causing objects to appear shifted or bent.
Why are bubbles formed when chalk is dipped in water?
Bubbles are formed when chalk is dipped in water due to the release of carbon dioxide gas. Chalk is made of calcium carbonate, which reacts with the water to produce carbon dioxide gas bubbles. This reaction is known as effervescence.
When the piston of a fountain pen with nib is dipped into ink and released by pressing the ink fills in the pen why?
When the piston of a fountain pen is dipped into ink and released by pressing, it creates a vacuum that draws ink into the pen through the nib. This is due to the pressure difference between the inside of the pen (lower pressure) and the outside (atmospheric pressure), causing the ink to flow in to equalize the pressure.

Why thermometer dipped in a liquid before use?
It is dipped into a solution known as an antiseptic. This solution kills any living bacteria that may be present.
Why is a shorn sheep dipped in an antiseptic solution soon after shearing?
Shorn sheep are dipped straight after shearing in a solution that contains a lousicide to kill lice.
What color does a strip of litmus paper dipped in acidic solution turn?
Litmus paper is blue when dipped in an alkaline solution, and red when placed in an acidic solution. The colors begin to merge when you test pH neutral liquids.
When an iron nail is dipped into copper sulphate solution after sometime the colour is changed into?
When a iron nail is dipped into copper sulphate solution after sometime the colour is changed into pale green.
What colour will universal indicator paper go if dipped into ammonia solution?
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
What happen when blue litmus paper dipped in soap solution?
If blue litmus paper is dipped in a soap solution, it is likely to turn red. This change in color indicates that the soap solution is likely acidic in nature.

When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
