What is observed when electric current is passed through copper sulphate?
When electric current is passed through copper sulfate solution, copper ions from the solution are attracted to the negative electrode (cathode) where they gain electrons and get reduced to form solid copper metal. At the same time, sulfate ions are attracted to the positive electrode (anode) and get oxidized to form oxygen gas. This results in the gradual deposition of copper metal on the cathode.
What happends when an electric current passed through a piezoelectric crystals?
When an electric current is passed through a piezoelectric crystal, the crystal experiences mechanical deformation or vibrations due to the inverse piezoelectric effect. This effect causes the crystal to change shape or generate vibrations in response to the electrical input. Conversely, when the crystal is mechanically stressed, it generates an electric charge along its surface due to the direct piezoelectric effect. This dual behavior allows piezoelectric crystals to convert electrical energy into mechanical motion and vice versa.
When did Sir Humphry Davy discover Sodium?
Sir Humphry Davy discovered sodium in 1807 through the process of electrolysis, in which he passed an electric current through molten sodium hydroxide (caustic soda) to isolate the metal sodium.
What does neon look like in its normal state?
Neon is a colourless , odourless gas. It glows only when an electrical discharge is passed through it; Neon lights.
Is neon shiny?
Neon is a gas- when electric current is passed through neon, it glows (think of an electric sign at a business) The term neon has been used to describe bright, vibrant colors that are eye popping.
What happens when an electric current is passed through the gas of vapor of an element?
When an electric current is passed through a gas or vapor of an element, it can cause the gas or vapor to ionize and emit light. This process is known as a gas discharge or glow discharge and is commonly seen in neon signs or fluorescent lights. The color of the light emitted depends on the element present in the gas or vapor.
What happens when electric current passed through acidulated water?
e
What happens when a electric current is passed through a coil of wires?
You generate a (stronger) magnetic field.
What happens when electric current is passed through fused sodium chloride?
During this electrolysis are obtained chlorine and sodium.
What happens when an electric current is passed through a solution?
Either the bulb will start glowing or the magnetic needle will show deflection
What happens when electric current passed through the colloidal sols?
The cations and anoin moves towards opposite electrodes ... or they will settle at the bottom
What is the difference in parallel circuit and series circuit?
In a series type circuit, the electric current passes through each element of the circuit (light bulb or whatever) in sequence; it does not reach any element until it has first passed through all the earlier elements. In a parallel type circuit, every element of the circuit receives its electric current independently. A separate wire connects each element to the source of the current rather than to the previous element of the circuit.
Do magnetic effect of electric current causes a change in colour in a solution through which electric current is passed?
i don't believe it does
What happens when electric current is passed through acidified water?
When electric current is passed through acidified water (a mixture of water and an acid such as HCl), electrolysis occurs. The water molecules (H2O) are split into hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode. The overall reaction can be represented as: 2H2O(l) -> 2H2(g) + O2(g).
Does copper get heated when electric current is passed through?
yes it does
What element produces a red light in advertisement signs?
The gas used to produce red light when an electric current is passed through it is neon.
What happens when a conductor is passed through a magnetic field?
When a conductor is passed through a magnetic field, an electric current is induced in the conductor. This is known as electromagnetic induction, a phenomenon discovered by Michael Faraday in the 19th century.
