Question

What volume of water should you add to 100 cm3 of a 1.16% m: V sodium chloride solution to obtain a 0.1 mol dm-3 solution? Calculate the dilution factor. Consider M (NaCl) = 58 g mol-1.

Answer 1

Answer:

The more the solution of a reactant is diluted, the slower the reaction will occur.

Explanation:

The key thing you need to understand here is that chemical reactions depend on reactant particles bumping into each other (collision theory).

The more concentrated a reactant is, the more likely it will be to bump into other reactants and product chemical change.

Here is video of a quick lab performed to test this. In the video, varying concentrations of Na2S2O3 are allowed to react with HCl. A timer is included in the video so you can see how the changing concentration changes the overall speed of the reaction!
