Solubility test in water.
All hydrocarbons are insoluble or sparingly soluble in water. For a quick confirmation Take few ml of water in a beaker and add a few drops of the unknown liquid to the beaker containing water. If both water and the unknown liquid get solubilised in water then it's definitely water. But if the unknown liquid doesn't get solubilised in water and gives a clear two-phase liquid then its a hydrocarbon.

A student was given a 10 mL sample of a clear, colorless liquid. She was assigned the task of identifying the unknown liquid and was told that the sample could be methanol (CH_3OH), acetone (C_3H_6O), or ethanol (C_2H_5OH). She decided to attempt to determine the molar mass of the liquid by the vapor density method, which involves completely vaporizing a small sample of the liquid, cooling it and determining the mass of the condensed vapor. She also collects the volume...

You have been given a 1 L bottle of a colourless liquid to analyze. Preliminary tests show that the sample is aqueous and upon heating to dryness a series of water-soluble salts collected on the bottom of the container. A few qualitative wet tests indicated that the sample was composed of the salts of halides (F–, Cl–, Br–, etc.), sulfate (SO42–) and ions of alkali metals (Li+, Na+, K+ etc.). The client would like you to quantitatively determine the concentration...

Suppose you have an unknown clear, colorless solution. In attempt to identify it, you add NaOH dropwise and find that a white gelatinous precipitate forms, but when more NaOH was added the precipitate dissolved again. To another test tube of the same unknown solution is added AgNO3 dropwise, and a white precipitate forms. What salt most likely comprises the unknown solution? Explain your reasoning (3 points) 2. Suppose you have a different unknown solution that you know to be 50/50...
