Question

Household ammonia solution (0.70 mol/L) may be diluted to prepare a hairbrush
cleaning solution (0.021 mol/L). What volume of household ammonia is required to
prepare 250.0 mL of a hairbrush cleaning solution? Give complete solution. ​

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!
