How does temperature affect the rate of reaction between sodium thiosulphate and hydrochloric acid? GCSE chemistry investigation Aim The aim of this investigation is to find out how temperature affects the rate of reaction between sodium thiosulphate and hydrochloric acid Apparatus * Sodium thiosulphate (Na2 S2 O3) * Hydrochloric acid (HCl) * Water * Piece of paper * Black marker pen * Conical Flask * Heat proof mat * Wire gauze * Bunsen burner * Tripod * Large beaker (x2) * Thermometer (x2) * Stop clock * Measuring cylinder (x3) * Beakers (x3) * Test tube (x2) * Blocks of ice Theoretical background I know that a number of things of things can effect the reaction rate such as the temperature. When the temperature increases the particles all move quicker, as they have more energy. If they move quicker they are going to have more collisions, increasing the reaction time. Another factor is the concentration of the solution, which also increases the amount of collisions, and therefore the reaction time. If a solution...
