The solution contains about 2% hydrobromic acid, about 0.5% dichloroethane, as well as small amounts of hydrochloric acid and bromoethane. How can the viscosity be determined? ?
Pynne viscometer! It’s not expensive; you can get it for just a few dozen yuan. It’s available at glass instrument stores! I hope this can help you! ! ! :lol:lol:lol:lol:lol
The key projects haven’t been built yet; there is no water
Take the viscosities of each pure component and calculate a weighted average
This is to make brominated polystyrene
