Diary of... a Y9 SCIENCE class - 1st February 2007

Hello,
Today we did an experiment which was very similar to the one the year 8's did, but our aim was different. We were looking at the reaction between acid and carbonates and one of its products: CO2 (Carbon Dioxide). We also put acid on chalk (calcium carbonate) and on egg shell (also calcium carbonate but crystalized) and we took the gas produce through a delivery tube to some limewater, which turned white because it reacted with it.
We also talked about safety in the lab, and Andy told a disgusting experience which, I'm sure you don't want it to happen to you. So: ALWAYS BE SAFE!!

See you tomorrow
