Reaction between HCl and Marble Chips

An Investigation into the effect of concentration of an electrolyte upon the amount of energy that is able to pass through it. Aim: To prove that the concentration of an electrolyte affects the current that can be passed through it Apparatus: Electrodes, Beaker, Lab Pack Measuring Cylinders Wires Materials: Hydrochloric acid (HCl), Water Diagram: Prediction: I believe that as the concentration increases, so does the amount of current passed through the electrolyte. I believe that …

…amp;lt;Tab/> Analysis: My graph proves that the concentration of the electrolyte does affect the amount of current that can pass through it. This is because there will be a greater number of molecules present to decompose and so more ions that are lost. This means that a greater amount of current can be passed through. <Tab/>There is one anomalous point when the concentration was 2mol/dm3,
