You can leave it in the open air if you are talking about a few ml. If you want to evaporate a few hundred ml its best to heat it over a fire
The bromophenol blue will turn yellow in the presence of an acidic solution like 0.01M HCl.
Hydrochloric acid (HCl) is considered the most volatile halogen acid compared to the other halogen acids such as hydrofluoric acid (HF), hydrobromic acid (HBr), and hydroiodic acid (HI). This is because HCl has a lower boiling point and higher vapor pressure, making it more likely to evaporate and form vapors at room temperature.
8.3 grams HCl (1 mole HCl/36.458 grams) = 0.23 moles HCl ------------------------
place small amount of dilute HCl on watchglass add butylamine one drop at a time Use indicator paper to determine when neutral., But remember to stir with glass rod in between drops. leave to evaporate in fume cupboard the end.
1M HCl means there is 1 mole of HCl in 1 liter of solution. To convert to 1N HCl, you need to consider the equivalent weight of HCl, which is its molecular weight as it is a monoprotic acid. So, in this case, 1M HCl is equivalent to 1N HCl.
The bromophenol blue will turn yellow in the presence of an acidic solution like 0.01M HCl.
.01m = 1cm
6
1 cm is .01m so 600cm*.01m = 6m =] -ray
i have Audi 01N and use it
HCl being a gas evaporate from aqueous solution and HNO3 may evaporate due to low boiling points at normal temperature so we observe fumes but H2SO4 is a non fuming liquid.
1cm = .01m therefore 1cm2 = .01x.01 = .0001m2
1 x 10^-14

Eurostar train from London to Brussels is 2h 01m, London to Bruges 3h 25m
Brownies do not evaporate. Only liquids evaporate.
