Write the balanced net ionic equation for the reaction that occurs when each of the following combinations from Part I (the seventeen known solutions) is tried. In some cases, the reaction is difficult to detect and you may not have observed a reaction. Record the observati ons that you actually made in the data table so that you can compare your unknowns with your ac observations. However, write a balanced net ionic equation in each of the following cases, even...
