1)Explain why aluminium chloride fumes in damp air
2)Aluminium metal is a good conductor and is used for overhead cabled.State two other properties that make aluminium suitable for this use
1) Aluminium chloride is a hygroscopic compound, meaning it easily absorbs water from the surrounding environment. When it is exposed to damp air, it reacts with the water vapor in the air to form hydrogen chloride gas. This gas can then react with more aluminium chloride to form a white mist of aluminium chloride fumes. The fumes are irritating to the respiratory system and can cause discomfort when inhaled.
2) In addition to being a good conductor of electricity, aluminium is also lightweight and has a high strength-to-weight ratio. These properties make it ideal for use in overhead cables as it allows for easier installation and maintenance compared to heavier materials like copper. Additionally, aluminium is resistant to corrosion, making it a durable choice for outdoor applications where it may be exposed to environmental factors.
