WebIndependent Variable (Variable that I am changing): The temperature of hydrochloric acid is to be decreased to 10ºC and 20ºC by adding ice cubes to the water bath (beaker) filled with water. Yet, for the rest of the experiment, the temperature will be increased from 30ºC to 40ºC to 50ºC by adding boiling water from a kettle to the water bath. WebIn a reaction between calcium carbonate and hydrochloric acid, the products calcium chloride, carbon dioxide and water are formed. I predict that the higher temperature of HCl acid, the higher the reaction rate will be, this is because at a higher temperature there will more fast-moving hydrochloric acid molecules per set volume. This means ...
