so on one side of the handle it saysquot;ceramic + ionOlivia Garden (c)2003quot;and on the other it saysquot;ceramic + ionthermal brushquot;
It's probably a round brush? The ceramic part heats up during blow drying and is used to straightenMake sure you use a thermal spray before going at it, it will really heat up and you don't want to damage your hair.

Strong HCL and NH3 (hydrochloric acid and ammonia) have strong and distinctive smells; so put a small amount of each of the clear, colourless liquids into a test tube and waft a little of the vapour towards youI wouldn't do this if you didn't know there weren't any seriously poisonous vapours in the list, by the way; and don't put your nose right over the tubesA rather safer way of doing this is to match up, in pairs, small amounts of the clear, colourless liquids and hold the ends of them close to each other; the ammonia and HCL tubes, when brought together, will create a smoke of ammonium chloride in the airThis tells you which are the HCL and ammonia, but not which is whichAdd each to the CuSO4 (see below) and NH3 will first form a precipitate and then redissolve it in excess NH3 to form an intensely blue solutionHCL and CuSO4 may form a slight precipitate, but this will not redissolve in excessCuSo4 is the only coloured solution in this list, so it's obviousMix it with each of the unknown clear liquids; BaCl2 and lead nitrate will form white precipitates with itTo tell the barium chloride and lead nitrate apart, add each to ammonia; the barium chloride will not form a precipitate, but the lead nitrate willOf the remaining, BaCL2 forms a precipitate only with H2SO4 and NA2CO3 (of BaSO4 and BaCO3, respectivelyThe precipitate from Na2CO3 will redissolve in HCL; the other one won'tSo now you know the Na2CO3 and the H2SO4The aluminium nitrate is the last oneAs a check, AL(NO3)3 will form a precipitate with NaOH that redissolves in excess NaOHI'm afraid that I can't help you with the precipitate colours, but I'm sure there are textbook and/or Internet sources for thatYou might find it a good idea to check this all out, by the way - my chemistry is a little rusty:) Thanks for the brain workout!
