Experiment: Halogenation: Electrophilic Aromatic Substitution to Yield 4-Bromoacetanilide The experiment we conducted (or tried to conduct!) Thus, NaCl, with its strong bonds, will not dissolve in acetone. At the next level of detail, I would point to the spectroscopic data, which has been around for over 100 years, as strikingly direct evidence for molecular orbitals. In fact, the opposite is true: 83 g of LiCl dissolve in 100 mL of water at 20°C, but only about 4.1 g of LiCl dissolve in 100 mL of acetone. The lead levels in water are expressed in units of parts per billion (ppb). Its chemical names are dimethyl ketone and 2-propanone. Acetone fixation is more effective at maintaining antigen integrity as compared to methanol and may be used as fixative if methanol fixation is ineffective. 1. Acetone is able to fully dissolve in water, meaning it's miscible in water. Get your answers by asking now.

Learn how to use the molecular equation to write the complete ionic and net ionic equations for a reaction occurring in aqueous solution. Styrofoam is made of polystyrene foam. b) Why is the iodide anion less stabilized than the sodium cation, when the two are dissolved in acetone? The attraction between acetone and an ion will be weak compared to something like water, which is extremely polar. With iodide, the solvate $\ce{NaI \cdot 3(CH3)2CO}$ can be formed, in which each $\ce{Na+}$ is coordinated by 6 acetone ligands via oxygen lone pairs, and the $\ce{I-}$ ions fill in the gaps between these octahedral units, being surrounded by the methyl groups of the acetones. (ºC) Solubility in water Butane CH3CH2CH2CH3 0 insoluble Chloroethane CH3CH2Cl 12 insoluble Acetone CH3CCH3 56 completely miscible Initially, that probably doesn't sound impressive, but many organic compounds don't mix well with water.
