Abstract: When ionic compounds are dissolved in water‚ they break apart into ions. In this lab the opportunity to mix two ionic solutions and observe the results was given. Some ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed‚ they form compounds that appear as cloudy or grainy precipitates. The objective of this lab was to observe the formation of compounds and to write the names and formulas of ionic compounds. It is also to
