Answer #1

First test is solubility test: both Rolaids (CaCO3) and cornstarch are insoluble in water, remaining all are soluble.

Second test is iodine test: cornstarch can give this test, Rolaids cannot, and it can be separated.

Sugar, salt, Epsom salt and salt petre are soluble in water. They can be identified by their pH value. Each of them has a definite pH value. Depending on the pH value we can find them. (Or) you can perform flame test also. Sugar under flame turns brown and then black. Salt (NaCl), salt petre (KNO3) and Epsom salt (MgSO4.7H2O) will each have a different color flame. Depending on the color we can find them. Salt (NaCl) will give yellow flame. Salt petre (KNO3) will give violet flame and Epsom salt (MgSO4.7H2O) will give white color.

The chemical box contains an “unknown” chemical that is a sulfate, carbonate, or phosphate salt. Using the procedures learned earlier in this experiment, determine which type of salt is contained in the unknown solution. Remember that the results need to match those from the previous experiments for a positive identification result. Other reactions may happen, but these results do not give a definitive answer with respect to what compound is in the solution. Use a permanent market to label three...
