SIMPLE REACTIONS Predicting the products of dissolution 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 10 6 mol/L major
species present when dissolved in water compound formula copper(II) chloride Cuc 0
isopropanol c,140 magnesium sulate MgSo
Solution
1) H2O,Cu(2+),Cl(-) {cucl2 will completely dissolve in water}
2) H2O,C3H8O, azeotrope of C3H8O {it will dissolve and form azeotrope}
3) H2O,Mg(2+),SO4(2-) {it will completely dissolve in water}
