Re: Help Sassi

If the stock solution of Hydrogen Peroxide is old, it may have turned into water, but this doesn't explain why the reaction was less when the concentration was higher though

Why Is It So?

Why do science teachers decide that the last few weeks of the last term are a good time to do projects with groups of 2 or 3 students? Especially when the budget closed on the 31st of October and they need stuff bought from the supermarket etc.

Re: What do you do when you KNOW the teacher is wrong

It depends on who they are there are a couple of teachers that I tell if they are doing something wrong and a few who i wouldn't dare say anything to unless it was going to cause a danger. Usually the mistakes are on the theory side of things as well

Re: Nitrile gloves dont protect you from........

Clear Polyethalene gloves, is what I have. They said they performed a test by pouring acid etc into different types of gloves and seeing what happened to the gloves. eg leaks etc. Still it pays to look at the MSDS and most if not all glove manufactors have data about it on their websites.

Re: Nitrile gloves dont protect you from........

The Chem. Dept. at the local Uni. said during a safety course that the best type of gloves in their opinion for handling the majority of chemicals was the cheap clear sandwich gloves. Plus they are not latex or powdered so if you have an allergy to either of those things that is also a good thing ab...

Re: fog machine

Just be careful if you were using it inside as we had one here set off the fire alarms and we all had to evacuate luckily it was the school holidays, so there were only a few staff around but the church group who hired the gym also had to evacuate as they were using the machine
