The solid is called a precipitate. Some other examples of precipitation reactions are given in Table 3. To be effective, these substances much have such high affinity for the respective ions that they overcome the high affinity of the calcium and oxalate ions for one another. As you proceed through the experiment, keep the following questions in mind. When you have finished the experiment, provide answers to them.
Hydrochloric acid is corrosive.
Wear gloves when handling it. In the event of skin contact, flush the affected area with copious quantities of cold water. Experimental Record all data and observations in your notebook. Swirl to achieve a slurry. With continuous stirring or swirling, add this volume of 6 M HCl to the calcium carbonate beaker using a Pasteur pipet.
