Lead Nitrate

[Catie]

Could other labbies please let me know what molarity of lead nitrate they use for Yr 7-10?

[macca]

lead(II) nitrate <0.003 M (<0.1% wt/wt) 7-12 years
lead(II) nitrate 0.003-0.03 M (0.1-1% wt/wt) 11-12
lead(II) nitrate 0.03-0.18 M (1-6% wt/wt) and above including solid Teacher only
lead(II) nitrate 0.18-0.45 M (6-15% wt/wt)

that's according to Riskassess

we use 0.001M. I try to get the teachers to make the kids wear gloves for it as well just as an extra precaution even though it is very dilute.

Until recently we were using 0.1M (oops!) , which had been set up in droppers before I started. Until I realised that 7-10s could only use <0.003M. So I set them up as 0.002M. Still works just as well for what they need it for.
