EDTA (Ethylenediaminetetraacetic acid) stock solution 0.5M pH8
http://openwetware.org/wiki/EDTA#0.5_M_EDTA_stock http://en.wikipedia.org/wiki/Ethylenediaminetetraacetic_acid
For 100 mL 0.5M EDTA:
- add 14.62 g EDTA (acid, MW = 292.25 g/mol) to a clean beaker
- add about 80 mL ddH2O
- add NaOH pellets slowly until the EDTA starts to dissolve (1-1.8 g)
- add liquid 10 M NaOH until pH is 8 (at higher pH EDTA is not very soluble.)
- add water to 100 mL
Autoclave to sterilize. The solution is stable for years at room temperature. This solution is used for making TE.
