Re: vernier go direct sensors feedback

We purchased the Dynamic cart and Track system which has been used in Physics and Investigating Science. Teachers and students found it easy to download software onto their laptops, set up and use.

I'm assuming you would need to follow the above guidelines and have a policy? Or is that only for vertebrates?
Not worth the trouble IMO

Re: Potassium Iodide

Potassium iodide is usually reacted with lead nitrate to give a bright yellow precipitate.
Could it be that your potassium iodide is contaminated?

Re: MTA products going downhill fast?

I am disappointed with the service at MTA. I have sent multiple emails to seek assistance to 3 different people (our assigned sales support person, technical person and general sales enquiry) over a period of a month and have as yet to hear from any of them. I will not be using MTA for any of our or...

Our Chem teacher did a demo using conc. HCl in a fume cabinet and a solution of 0.1M cobalt chloride. She also heated it and put it in an ice bath. She said it worked well.

calcium granules

Hi everyone,

I have an old bottle of calcium granules that have turned completely white (they look like coconut flakes). There is no reaction with water or dilute HCl. Any ideas about how to dispose of would be much appreciated.

Re: SDS

My understanding is that you need a Chemical Register with SDS and correct labelling for all hazardous substances whether bought or made up. So you need to check whether what you are making up and using is hazardous.

Re: Manganese dioxide

We use it for junior classes but I have a small amount already deposited in the bottom of the test tube for the students to just add the hydrogen peroxide to and test for the oxygen liberated. Saves on students using a ridiculous amount of the manganese dioxide powder and all the mess!
