WebReaction #1: - When we first mixed the potassium chromate with sodium hydroxide in the first test tube, it appeared that no visible changes - In the 2nd test tube, once we mixed the potassium chromate with sulfuric acid, it turned into a more orange/dark yellow color - This happened because K2Cr2O7 was formed. Elemental potassium does not occur in nature because of its high reactivity. It reacts violently with water (see section Precautions below) and also reacts with oxygen. Orthoclase (potassium feldspar) is a common rock-forming mineral. Granite for example contains 5% potassium, which is well above the average in the Earth's crust. Sylvite (KCl), carnallite (KCl·MgCl2·6H2O), kainite (MgSO4·KCl·3H2O) and langbeinite (MgSO4·K2SO4) are the minerals found in large evaporite dep… ct13 9nl
