Why is the disposal of the used conducting solution a concern to the environment?

Why is the disposal of the used conducting solution a concern to the environment?

Answer. (d) In electroplating factory, the disposal of the used conducting solution is a major concern because it is a polluting waste, therefore it should be disposed off according to the disposal guidelines of the local authority.

Do the disposal of used conducting solution is a major concern in the electroplating factories?

In the electroplating factories, the disposal of the used conducting solution is a major concern. It is a polluting waste and there are specific disposal guidelines to protect the environment.

What happens when electric current is passed through a conducting solution?

The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of a gas may be formed on the electrodes. Deposits of metal may be seen on electrodes. Changes of colour of solutions may occur.

What effect does the current produce when it flows through a conducting solution Class 8?

What effect does electric current produce when flowing through a conducting liquid (or conducting solution)? Solution: When an electric current passes through a conducting liquid, it gets decomposed into ions. The conducting solution has free ions available which conduct electricity.

What word is used to describe an object which does not conduct electricity?

Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Does pure water conduct electricity if not what can we do to make it conduct?

Pure water does not conduct electricity. It does not contain salt and so it’s a poor conductor of electricity. To make pure water conducting, we can add salt to it.

What type of chemical reaction takes place when electricity is passed through water?

decomposition reaction
Electrolysis of water is a decomposition reaction ; a single reactant breaks down into more than one product. The breaking down of H 2 O into H 2 and O 2 by passing electricity is known as electrolysis of water.

What are the advantages and disadvantages of electroplating?

What are the advantages and disadvantages of electroplating? Electroplating has many advantages such as the ability to layer very thin metal to surround objects and enhance their looks. It also has its disadvantages such as the lack of a thick shell for example!

What happens when current is passed through body?

Electrocution or so called electric shock occurs when current passes through the human body. The real measure of electrocution intensity is directly related to the amount of current (Ohms law),in amperes, that passes through the body, and not to the voltage.

Is milk a good conductor of electricity?

Milk is a good conductor of electricity because it contains water and lactic acids and other salts.

What’s the proper way to dispose of laboratory waste?

Laboratory Waste Disposal Procedure Summary Make sure the materials placed in the municipal waste are suitable for this type of disposal, especially: Do not place any liquids in the municipal waste. Do not dispose of chemical waste, including stock containers with unused product, in the municipal waste.

What are the disposal procedures for radioactive waste?

Radioactive waste – manage radioactive wastes in accordance with the Radiation Safety Manual. This type of waste may only be removed by Environmental Health and Safety personnel. Biological waste – manage biological wastes in accordance with the Biohazardous Waste and Sharps Disposal policy.

How is conducting solution disposed in electroplating factory?

Answer. (d) In electroplating factory, the disposal of the used conducting solution is a major concern because it is a polluting waste, therefore it should be disposed off according to the disposal guidelines of the local authority. When electric current is passed through a conducting solution, there is a change of colour of the solution.

What are the cleaning and waste disposal procedures?

Healthcare and other care facilities should follow general cleaning procedures. Some facilities require specialised cleaning procedures. Waste disposal is also important for infection control. Different types of waste – general, clinical and pharmaceutical – have different waste management procedures that need to be followed.
