Planning (concentration) Aim: In this investigation my aim is to find out how concentration affects the rate of reaction between HCL and marble chips Hypothesis: My hypothesis for this experiment is: "As the concentration is increased so will the rate of reaction" Prediction: The more the concentration is increased of the acid the greater will be the rate of reaction, because if you increase the concentration of the reactant, the PH is a measure of the concentration of the hydrogen ions and roundabout the strength of the acid this also increases the number of collisions between the particles and as a result increases the rate of reaction. This explains why the greatest rate of reaction is almost immediately after the reactants are mixed i.e. the reactants are both at their maximum concentration. Independent variable: For my experiment my independent variable will be the constant changing of the HCL Dependant variable: For my experiment my dependant variable will be the time...
