Step-by-Step Solution:
Step 1 of 3
Answer :
(a) 0.15 M NaCl
NaCl → Na{+} + Cl{-}
(0.15 M NaCl) x (1mol Cl{-} / 1mol NaCl) = 0.15 M Cl{-}
(b) 0.15 M CuCl2
CuCl2 → Cu{2+} + 2 Cl{-}
(0.15 M CuCl2) x (2 mol Cl{-} / 1 mol CuCl2) = 0.30 M Cl{-}
(c) 0.15 M AlCl3
AlCl3 → Al{3+} + 3 Cl{-}
(0.15 M AlCl3) x (3 mol Cl{-} / 1 mol AlCl3) = 0.45 M Cl{-}.
