Lithium carbonate reacts with citric acid. Dry lithium carbonate (Li2CO3) is placed in a balloon, which is then attached to an Erlenmeyer flask that contains 20 mL of saturated citric acid (H3C6H5O7). After the balloon is turned upright, lithium carbonate pours into the acid. In the reaction, H3C6H5O7 + Li2CO3 -> Li3C6H5O7 + CO2 + H2O, carbon dioxide gas is produced and the balloon is inflated. The left frame shows the result when 0.025 mol of lithium carbonate was used, while the right frame shows the result when 0.05 mol of lithium carbonate was used. The balloon size in the right frame is noticeably larger because more carbon dioxide is produced in the second case. This is an example of a carbonate-acid reaction, which in itself is a double-replacement reaction followed by a decomposition reaction. | |
