Bromine water at 0.1M | Science Technician Community
Looking at the cleapss recipe for bromine water it only gives the solution for making up 0.02M as a litre, for a displacement reaction I need 0.1M so if I follow the cleapss recipe for making up 0.02M but only make 200ml that would be 0.1M wouldn't it? I would prefer not to make more than what is needed as I don't want it hanging around after.

Bromine Water Test (Saturation Test)
A bromine water test is employed to assess if a hydrocarbon is saturated or unsaturated. Since unsaturated hydrocarbons include at most one Carbon-Carbon double bond, which is fragile, an electrophilic addition using halogens, hydrogen halides, or water may be achieved without heat, making it straightforward to check for alkenes.
