Question

The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H20) Note: "major" chemical species are those present in concentrations greater than 100 mol/L major species present when dissolved in water compound formula acetone (CH,) CO methanol CH,OH copper(II) sulfateCuso

Explanation / Answer

a)

acetone is molecular, not likely to dissociate, so

(CH3)2CO will be present as well as water

b)

methanol is molecular, will not form any kind of ions, then

methanol + water will be present in the solution

c)

CuSO4 is an ionic compound, iwll form ions in solution

Cu2+ and SO4-2

therefore, choose Cu2+ and SO4-2 ions
