CHEMICAL TESTING FOR ANIONS INTRODUCTION; In this investigation we are going to test for anions present in various salts. Such as we have known, the charged particles are called ions. Positive ions are called cations because they travel towards the cathode, such as: aluminum, ammonium, calcium, copper, iron (II), iron (III); Negative ions are called anions because they travel towards the anode, such as: carbonate, chloride, iodide, nitrate, sulphate. Anions - the Negative ions are called anions because they travel towards the anode. Sulphate ions and nitrate ions are very difficult to discharge. When solutions of sulphates and nitrates are electrolyzed, hydroxide ions are discharged instead, and oxygen is evolved.Cations are the charged particles that contain positive ions and anion are the charged particles that contain negative ions. In this experiment, we are going to use the tests of anions of various metals slats Potassium chloride, Iron chloride, Sodium sulphate Calcium carbonate and Lead...
