Another clip from yesterday’s activity. Great effort taking particular care with eye protection in the lab. Well done boys, very professional.
- Hydrogen is a light gas.
- It can be collected in an upturned test tube
- We can make small samples by dropping a reactive metal such as magnesium into dilute hydrochloric or sulphuric acids.
- Mixtures of hydrogen in air are explosive in the right amounts giving a characteristic pop when a flame is brought close.
