What mass of aluminum will be needed to react completely with 48.0 ml of 1.55 M
Reaction: 2 Al + 6 HCl 2 AlCl3 + 3 H2
L mol mol ratio mass
0.048 L HCl
1.55 mol 2 mol Al
6 mol HCl
27.0 g =.670g Al
Salts containing alkali metal cations or ammonium are soluble.
Salts containing nitrate or acetate anions are soluble.
Salts containing chloride, bromide or iodide are soluble. (Except for Cu+, Ag+, Hg2+2
Like Dissolves Like- This means polar solvents like water will dissolve other polar
solutes as well as ionic substances. Water(highly polar) will dissolve ammonia(polar)
and salts(ions are extremely polar)
Non-polar solvents will dissolve other non-polar
