If I have a solution that is 0.50 mol/L, and I then take 35 mL of this solution and make it up to 175 mL total volume by diluting with water, what is the new concentration? (Hint - you will need to use ciVi = cfVf )
Answers
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
N
a
2
S
2
O
3
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
