T An Investigation To Show How Changing The Temperature Of The Hydrochloric Acid Affects The Speed Of The Reaction Between The Marble Pieces And Hydrochloric Acid Variables In this experiment there are many variables which can be sorted into two groups-continuous and non-continuous. The variables are listed: -Size of conical flask (non-continuous) -Acid concentration-add water to the Hydrochloric Acid to lower the concentration (continuous) -Acid temperature- e.g. 30 C (continuous) -Type of acid- e.g. Hydrochloric Acid, Sulphuric Acid and Nitric Acid (non-continuous) -Size of Calcium Carbonate chips-surface area of Calcium Carbonate (continuous) -Mass of Calcium Carbonate (continuous) -Acid's volume- e.g. 30cm (continuous) -Form of Calcium Carbonate- powder or stones (non-continuous) The variable that I have decided to change in this experiment is the temperature of the Hydrochloric Acid. Quantitative Prediction In this experiment I predict that if I increase the temperature of the Hydrochloric Acid by 10 C, then the time taken for the reaction between the marble (Calcium Carbonate) pieces...
