Then panic about the dry beaker and dumb cold water on it. Sodium silicate (Na2SiO3), for example, reacts as shown below. A quick one pertaining to HF itself was the fact that she knew it reacted with glass but went ahead and did her reaction in a beaker while heating it "just Video should be smaller than 600 MB/5 minutes Photo should be smaller than 5 MB Video should be smaller than 600 MB/5 minutesPhoto should be smaller than 5 MB Related Questions

You may have been able to move it before, but I wouldn't count on it working all of the time. But, HF, due to the already strong bond between the H and F (F is too electronegative for its own good) is not a strong acid otherwise.

Even so, Borosilicate glasses tend to be brittle, leading to the use of tempered soda-lime glass with tweaked LEC's (additives to alter the linear expansion coefficient) for its greater mechanical strength Beer POLL: Do you prefer to drink it from the source, bottle, can, tap OR a glass? Low concentrations should be okay, for short periods of time. show more Hydrofluoric acid, HF(aq), cannot be stored in glass bottles because compounds called silicates in the glass are attacked by the HF(aq).
