* Research question:
Does the change in concentration of sodium thiosulfate and the fixed concentration of hydrochloric acid result a change in time taken for the yellow sulfur precipitate to form, thus lead to a change in time taken for the cross to disappear and the rate of reaction?
* Independent variable: The concentration of sodium thiosulfate / M.
* Dependent variable: The time taken for the cross to disappear / second.
* Controlled variables:
* The concentration of hydrochloric acid / M.
* The temperature in each conical (Erlenmeyer) flask prior to every reaction / oC.
* The absence of unnecessary substances or ions.
* The angle to view the cross.
* For many reactions involving liquids or gases, increasing the concentration of the reactants increases the rate of reaction. In order for any reaction to happen, particles must first collide. This is true whether both particles are in solution, or whether one is in solution and the other a solid. If the concentration is higher, the chances of collision are greater .
* In the reaction between
