Borax (Sodium Tetraborate Decahydrate - Na2B4O710H2O)
Acetic Acid* - CH3COOH(aq)
Sodium Silicate Solution - Na2SO3(aq)
Ethanol* - C2H5OH(aq)
* These MSDS sheets are for the pure undiluted reagents.
The MSDS for acetic acid is for glacial acetic acid, which is 99.5 to 100% pure acetic acid. This experiment only calls for a 5% acetic acid solution (household vinegar) which is less hazardous.
The MSDS for ethanol is for pure, denatured ethanol. This experiment only calls for a 50% solution, which is less flammable and less hazardous.
